HARRASSMENT!!!

I had contacted RCS three months ago via email, advising that I was able to pay an amount of R 500.00 each month until my Game Account was paid in full and then wished to close the account. No-one has bothered to respond to my email. I have been paying R 500.00 each month as I stated and have proof of payments to prove this. I receive up several calls a day, every single day, from RCS about my Game account. I tell them the same thing every time and every day i get several calls a day. I am fed up as this is impacting my work as we are not allowed to take personal calls at work and i am being questioned why i am running for my phone so many times a day. I have not refused to pay and i have not stopped paying, i have arranged to pay R 500.00 a month which i am duly doing. Noone can tell me why i am getting several calls a day and why i am being harassed. I expect this to stop and i intend on lodging an official complaint with the consumer council as this is blatant harrassment!
