Terrible experience from Vox accounts department and technical issues.

After a terrible experience with Vox last month, getting my line downgraded(They cancelled it completely instead due a technical issue on their end), I now have a new sub which is active and working. However due to the same issues it seems, they have double-billed me. Since I get billed in advance, I already paid for the old sub for the month of April 2024. It was then suspended and cancelled before 01 April, and a new line was put into place for April, which I got billed for. However, they did not credit me for the previous invoice and line which I had already paid for and was unable to make use of, for the same time period. Now, weeks later I get an account statement asking for additional money for April, which should not be the case. Terrible customer service. I even called in and every time I call in over the past two weeks, consistenly must wait for at least ten to 15 minutes, or the call drops. I would not recommend VOX to any new customer.
