Ignoring Requests and Poor customer service

12.10.2015 I contacted RCS to ask what the bal is so that I could pay it up.My account was closed and that the last payment received from MBD was on 19.06.2015. I was told that my balance at RCS is -R7.41.I was told contact MBD,they sent the acc back to RCS as it was paid up.I contacted MBD on 13.10.15.I was informed that my account is not with MBD and that it will be escalated for someone to send me a paid up letter.I asked her about the money paid to MBD from July-September 15 for my RCS account, i was told that they cannot pick anything up the system.I heard nothing back.On 29.10.15 I contacted MBD again and spoke Abram.I explained the entire situation and he said he would investigate only to inform me via email on 29.10.2015 that my account is paid up and RCS has my account at -R7.43.On 02.11.15 and 05.11.15 I sent emails asking what happened to the monies paid to MBD in July/Aug/Sept 2015.I received no response.On 25.11.15 I contacted MBD and spoke to 2 people who sent me the paid up letter.This letter does not confirm when this account was paid up,nor does it confirm or state the balance on this account.Avoiding my questions with no proper explanation is unacceptable.
