loan account

I had a loan with Capitec bank, been paying well every month, thing's started going wrong when my salary date change, my account started falling into arrears for two moths I phoned their collection department for payment arrangements, this was in November 2014 made arrangements to pay end of November ,went to Menlyn branch to make a payment as promised, payment couldn't go through we thought it was a network or something ,not till one Of the consultant makes a call to their head office to find out what the problem could be, was surprised to hear that my account has been handed over to MBD attorneys, couldn't understand why cause I had arranged, they gave me the number to call, I did phone MBD attorneys the following day, was told that they don't have my account with them, I went back to Capitec to find out what is going on, was again told to wait for MBD attorneys to contact me, I am still waiting since last year till today to be contacted so that I can resolve this, I phoned MBD again in February and beginning March they still don't have my account with them, they told me that they will check and get back to me, what can I do to resolve this? I have been running up and down .
