Bad service consultants are rude

I cannot wait to cut ties with Absa the service I have received is unacceptable they are charging me interest daily for their mistakes I have switched to FNB because of their bad service I am not getting my statement for my vehicle account and the instalment increased without notifying me to pay more, there is no communication until I received an SMS that I'm under their collection department for outstanding payment I have never skipped an instalment always a good payer but this will affect my credit record because of their poor service to the community and my collogues agree with me. i have paid the account but i want absa to reverse all the interest charged into my account for lack of communication and poor customer service not receiving a statement and paying with instalment they gave me at first was nit my fault they are notification they needed to send because I'm paying with EFT .
