Non existent Accounts Service

I was on Zoom Network. I got a call to say that Zoom is migrating their customers to Vox in December, no specific date given. At the end of November I paid a full month payment to Zoom to prevent disconnection. On the 12th of December I was charged a pro rated amount by Vox. At the end of December I was charged another, presumably and rightly so for January. I mailed Vox and Zoom to tell them there should obviously be some recon done as I had paid them both for December. I mailed on 4th of Jan and yet to receive a reply. Fast forward to this week and I receive an invoice from them. It is an amount for 2 monthly payments. I phoned the call centre to query, they said they can see 2 accounts on my name. I said this is incorrect. I was told to hold, however I was put back in the queue. I posted on their page on FB. Was told someone will get hold of me. Still waiting. Guess what, my next payment will go out for DOUBLE the amount and everyone knows how hard it is to get a refund....if any.

Only with Vox for 2 months not and ready to move!!!!

It would be remiss of me not to mention that I have had great service with their technical teams. Unfortunately their accounts team leaves a lot to be desired.
