Apparent Out Standing Debt

So to start beginning of the year i get told i have out standing debt. call center which only told me my contribution has gone up and i have to now pay 2129 every month and no one can tell me why. Come end of June after paying my contribution i discover that the payments are only 1924 i contact the call center once again and a woman informs me i have been paying to much and i have a credit of 2000 odd and should at the end of July only pay 685 and then from end of august continue paying as normal the 1924.

come end of July i do what i was told and pay the 685 now on the 14th of august in the middle of the month i get told i am once again in debt by 419 rand and that my scheme had been suspended on the 1st of august (so they only let a person know this 14 days after they suspend your scheme).

Once again i contact Bonitas only to get someone that is absolutely rude that tells me he cant get hold of my credit controller but some friends of his that also work with credit (but not my credit) say i should just to solve the problem pay the money and will have no further issues.

No one can tell me why i keep getting told different stories or why i could pay 685 and the built up credit would cover the rest of the contribution at the end of July only to get once again someone that cant help me with my problem and when i ask to speak to someone who can help im told no i am speaking to them and i must pay the money.
