SA Home Loans Credit/Cancellation dept bullies

I sold my townhouse (bonded to SAHL) and duly gave SAHL notice to cancel my bond.My husband made advance payments into my bond of R195 000 on 10 March 2015 and a further payment of R500 000 on 31 March 2015 bringing my loan account approximately 70 months in advance.I querried why this amount paid did not reflect on 31 March and is still awaiting a reply.On 7 April my husband paid another two amounts R150 000 and R90 000 DIRECT Standard Bank to Standard Bank(where SAHL banks)...bringing my home loan an additional 24 months in advance.Nevertheless I received an e mail from SAHL alleging that I am in arrears with R1 375.05 and they have/are going to report me to ITC and this arrears will impact on my payment profile.My husband was so upset that he paid off the loan account yesterday and again it does not reflect.The way SAHL handled this matter is seriously questionable and I want to know where they have been keeping the funds as it is highly irregular and they make their calculations not taking into account payments made.
