Bad customer service from Voxtelecom

I have billing queries with Vox with regards to my website hosting and have had no luck in sorting out the issues. In the meantime my websites are down and I am seriously loosing income. They are currently charging me for the hosting of 4 x websites when there should only be 2. The one website I am being charged for (since 2012) does not exist (there is only a domain name), and the other was sold to to another person 2 years ago (2016). They don't respond to emails and don't take calls. I am dealing with the credit control dept in C.T. for weeks now with no luck. When I said I want to move to another service provider, they were quick to add cancellation charges for the remainder of the contract period. They are the worst people I have ever encountered to sort out queries. To future customers, stay away from Vox, you will receive the worst customer service ever.
