Between January and March 2026, I surveyed 100 UK business owners (10-200 employees) about their phone provider experience. The results explain why the VoIP industry has a customer satisfaction problem — and what the best providers do differently.
The Survey
100 UK businesses. Anonymous. One question per topic. Responses rated 1-5 or free text.
Top 10 Complaints (Ranked by Frequency)
#1: "Support takes too long" — 73% cited this
| Wait Time Experienced | % of Respondents | Satisfaction |
|---|---|---|
| Under 5 minutes | 12% | 4.6/5 |
| 5-15 minutes | 28% | 3.2/5 |
| 15-30 minutes | 35% | 2.1/5 |
| Over 30 minutes | 25% | 1.3/5 |
The correlation is stark: support wait time is the #1 driver of satisfaction. Every minute over 5 drops satisfaction by 0.15 points.
#2: "Price increased without warning" — 61%
Quotes from respondents:
- "Went from £22 to £29 overnight. No notice."
- "Renewal price was 40% higher. Take it or port out in 30 days."
- "Hidden fees appeared after month 3 that were not in the original quote."
#3: "Mobile app is unreliable" — 58%
| Issue | % Experiencing It |
|---|---|
| Missed notifications (app did not ring) | 42% |
| Poor audio quality on mobile | 31% |
| App drains battery | 27% |
| App crashes | 19% |
#4: "Cannot get a straight answer on pricing" — 52%
- "I asked 3 times for the total cost. Got 3 different numbers."
- "The quote had 14 line items. I still do not know what I am paying."
- "They said £20/user. My first invoice was £34/user."
#5: "Locked into a contract I want to leave" — 48%
| Contract Length | % Wanting to Leave Early |
|---|---|
| Month-to-month | 8% (and they can leave) |
| 12-month | 22% |
| 24-month | 38% |
| 36-month | 61% |
The longer the contract, the more likely the customer wants to leave. This is damning evidence that long contracts exist to trap, not to serve.
#6: "Features I was promised do not work properly" — 44%
Most common broken promises:
- "CRM integration was supposed to be native. Turns out it is via Zapier and breaks weekly."
- "Video was included but limited to 45 minutes and 10 participants."
- "Call recording works but I cannot search or export recordings."
#7: "Porting was a nightmare" — 41%
Average porting experience rated 2.4/5. Common issues:
- Took longer than promised (78%)
- Numbers went dark during port (23%)
- Old provider obstructed the process (34%)
#8: "No visibility into call data" — 38%
"I cannot tell you how many calls we missed last week" — 38% of business owners said this.
#9: "System went down and support did not know" — 31%
31% experienced an outage where they had to inform the provider, not the other way around. No proactive notification.
#10: "Training was nonexistent" — 28%
"They set it up and left. My receptionist figured it out by trial and error over 2 weeks."
What the Top-Rated Providers Do Differently
The 12% of respondents who rated their provider 4.5+ shared these traits:
| Trait | Top Providers | Average Providers |
|---|---|---|
| Support wait | < 5 minutes | 15-30 minutes |
| Pricing model | All-inclusive, published | Complex, variable |
| Contract | Month-to-month available | 12-36 month minimum |
| Mobile app reliability | > 95% notification success | < 80% |
| Proactive outage notification | Yes | No |
| Onboarding training | Included, personalised | PDF manual or nothing |
The Takeaway
The VoIP industry has a service problem. Most providers optimise for acquisition (get the customer signed) rather than retention (keep the customer happy). The symptoms: long contracts, hidden fees, slow support, broken promises.
The cure: choose a provider that competes on service quality, not contract lock-in.
DialPhone was built specifically to address these 10 complaints. 3-minute support response. Published pricing with zero hidden fees. Month-to-month contracts. 97% mobile app reliability. Managed onboarding with training included. Because the best customer retention strategy is not a contract — it is a product worth staying for.
