Bad service

I was billed from 23rd March as the line was active even though I only received my rooter on the 29th and I only start using their service from the 3rd of April. I have been asking for someone to get back to me regarding my credit request since beginning of April on email and calls. I got a couple of read receipts and even a couple of delete without reading receipt, but up to today no one has rep****. And then they have the audacity to bill me again for a full month after they over charged me the previous month. I would have never changed to Vox if I new it would be such a headache.
