No Customer service received

For the last 5 moths I have been experiencing the same issue with Supersonic month after month. Every single month I receive a bill saying I am a month in arrears where I have to send the proof of payment made. I am now at a stage where I send the proof of payments for the entire year every single time I make a payment because the accounts department does not have the competency to reconcile.

Furthermore when I call to have the matter resolved (where I am decent with them everytime) the consultants seem annoyed that I dare question or call them.

I have asked that a debit order be set up , where no one called me to do this or confirmed that something of the sort has been done. I believe I have been patient with them but up to date have not received the service I am paying for. Maybe if they learn how to reconcile payments to their accounts I will get some sort of service from Supersonic

We just want the matter resolved as we are working from home and can not afford not to have internet
