Worst Service Ever! Empty Promisses

RCS is quick to ask for money, but when you ask them for something, they have so many stories. My RCS account was paid in full in March this year and now when I ask them for a letter stating that my account is closed, they cant help you. When you call them, they let you hold on for more than a half an hour and then when they say they are sending the letter, they never do. You waist all your airtime ons RCS and when they say they will call you back they also never do. Their service is utterly poor. I recommend that nobody should use RCS as they make promises they cant keep. We are in the prosess of buying a house and RCS is the only one that is keeping me from getting that home loan.
