Very disappointed

I have a credit card with ABSA and my account is in arrears, they have handed over my account to different attorneys. I received an email from 1 company asking me to make arrangements for payment within specific days and immediately I rep**** to their email but never got any response few days later they send a different company for collection, same thing happened I rep**** to the email but up until now no one has responded to my email, so how am I going to resolve this issue, if no one is willing to help or reply to my emails? What irritates me the most is that they keep sending one and same thing every day and when I reply as stipulated they never respond.
