RCS - Poor Customer Service

On the 30th March I paid my account and then sent them the proof of payment. After sending over 40 e-mails and speaking to so many different agents my payment was updated on the 23rd April, I was then advised that all bureau listings and additional costs will be reversed. I was then given an easy pay number to use. I paid my account again on the 24th April and sent the proof of payment to one of the managers that was handling my previous query, he then rep**** that the easy pay number that was given to me was incorrect, apparently they made a mistake and send a whole lot of customers incorrect easy pay numbers. He advised that my proof of payment was sent to the I.T department to update. Its been 8 days and nothing has been updated as yet. I am so sick and tired of RCS, such a big company has such *********** staff. How is it that even after a manager escalated the matter no one can update my payment. I have been a loyal customer to the RCS group for many years and this is so disappointing to know that they have broken my trust in them. I dont believe that this is how loyal customers should be treated.
