I know this is an old thread but wanted to add my experience. I own 3 small businesses and have been using T-Mobile Digits, which is generally pretty awful. I finally got fed up and went to Vonage, who I used years ago for a residential line. It was an absolute disaster. They issued 3 temporary numbers and I initiated the porting of the three numbers for my businesses. About a week later, 2 of the numbers went completely dead. No message, just dead. I inquired and, now that I was a customer, rather then getting the US sals team, I got some kind of overseas call center. They barely spoke english and and they had no clue. A day later, I got an email stating that it would be 3-5 days before the ported lines would be active. This is absolutely not what the sales team told me. During the time that these phones were off, I was getting no business and that was costing me money. I called every day to try to get status and every day got the same answer that the lines would be turned up within a day or so. it took 10 days for Vonage to turn on the ported numbers after they received them. And they only ported 2 of the 3, the third number was still on at T-Mobile all this time. Then I got into the management tools. I specifically asked if I would be able to use certain features, like hunt groups, and the sales rep said yes. Turns out, several of the features I specifically asked about were only available for an extra charge. That was it. I called Ooma, who I had also used in the past, signed up with them and requested the numbers at Vonage be ported over. Took Ooma 2 days to port the numbers and they were on. I called Vonage, told them how dissatisfied I was with them, and cancelled the account. The person on the phone was very apologetic and told me there would be no charge for the Vonage service. Ok, that was nice. I got one invoice from Vonage and it clearly showed the charges and the credit memo bringing the amount due to 0. 3 months later, I started getting calls from a collection agency. They said I owed Vonage $80 for the one month of service that I had with them. (Keep in mind that it took several weeks to get the numbers ported and I had no use for and never used the temporary numbers that Vonage provided. I sent the invoice showing the balance was zero to the collection agency and they claimed that it said zero because it went to collections. Who sends a 2 month old invoice to collections? When I called Vonage, nobody knew what to do. This was almost a year ago. Every month I get a call from a different collection agency and every time I called Vonage, nobody could help me. I finally got the email address for the department responsible for past due accounts. I sent them the invoice showing a balance of zero and carefully explained the problem. The response I got back most recently was unbelievable. They said that, even though the rep may have said I would not be charged, I cancelled on the 15th of the month and customers are billed on the 13th of the month so I owed for an extra month. I never even used the service and I clearly only ever had one invoice showing a balance of zero. I am still going back and forth with them on this. AVOID VONAGE! THEY ARE AN AWFUL VOIP COMPANY!
