Disappointed with the service received

I made an EFT on the 20/08. The 17/09, I received an sms stating that my account has not been paid. I called the call centre to find out why, Ramona said I need to send my proof of payment through to pop@rcs & it would take 10 days to resolve. I pleaded for it to be sooner, my next payment was almost due. She promised that if I copy her in the email, she'd try to speed up the process.<br> 10 days later, I went to make a purchase. My transaction was declined. I had to leave the building material (embarrassing), Called RCS . An agent said my payment still not reflecting, got another email address to send proof of payment to & said it should be sorted in 15mins. I called back AGAIN, spoke to Mxolo, she says the documents I sent were not correct & I would need a 'tracking something' at the branch. I was upset. Extremely. if the job was done properly the 1st time this wouldnt be an issue. i had to call 3times! I told Mxolo I want a senior to call me back, she said I'd get a call Saturday. I AM STILL WAITING- its Monday already. No one wants to take ownership. Quick to make the sale, but poor on delivery! Can someone who knows what they are doing please help me sort this out.
