RCS IS A NIGHTMARE!!!!

This thing doesn't give me an option of rating NO STARS. I would not even give RCS one star. I have been struggling to close my account since the 17th of May 2018 after settling both my Game Card ( ********** ********** 27668) and my RCS Card ( ********** ********** 73810). I have sent two emails already requesting this to be done and I have been phoning since 8:00 this morning, just to be placed on hold and never being answered again. They keep on telling me they will put me through to the department closing the cards, but that person never answers. All together today, I have been holding on for 73 minutes and then later cut the call, because I am using my cellphone to do this. RCS is very quick to offer credit and lift your credit, but when it comes to general admin, they SUCK. I need to close this account, ASAP. And if a debit order goes off my account this month, the hell is going to be loose! Please assist.
