Closure of RCS Account with no success - Unacceptable

To rid myself of debt I have fully paid my RCS account and have been trying for a whole week to have it CLOSED with no success....I have tried first thing in the morning and staying on the phone with repeated useless information and no answer from the other side..High call volumes is what is also repeated yet I'm on the phone the minute the call Centre opens....Is this a tactic to get people to keep accounts. Where is your customer service...I have left messages to close my fully aid up account on you website as well as emails sent to RCS...what is happening?????????????????????????????I need answers....How difficult is this process??????????????????
