1 says pay x, 2 months later that was wrong

Another month has passed & my husband is still earning R9000.I am paying off his debt, my debt, the short fall on the bond,& everything else that goes with living under a roof & getting to work & back to earn the money that pays for essentials.We are 4 adults in the house.I have paid R100 & R150 off on the arrears which if you've been in our shoes is a lot.Today we receive an e-mail saying it's not good enough \We require additional payments of a significantly higher amount to commence as of July"and please do not bother telling me that is not what was being said.I e-mailed proofs of payments but it got allocated willy nilly.I paid the amount stipulated in an e-mail dated 30th April and now in June I'm told that the reason my R150 arrears payment was not allocated to arrears is because I short pd May 1st's installment.Seriously? Perhaps I should do your books for u.I'm sick of being told \""thank you\"" but it's not good enough.Perhaps I should talk in a different language?I can't afford more until the house is sold.Again I point out that other customers were given up to 6 months of no bond"
