bad service, ridiculous charges for collection don't know what for

i recently discovered that RCS group bought Adgars that going down. I have a account with Adgars that I am paying well since I use it. Since RCS took over I am called every day , every hour by agent want arrangement for account that I pay monthly. RCS is know charging me R32 x 2 in a month as collection fee, R3 for sms, and other fees that I don't know. Is this how Adgars thank their customers because they no longer in market and in business, they hand over client to calling and add interest for no reason. I have agent to check my monthly INSTALLMENT none failed to tell instead what arrangement. what arrangement should be done in account that I've been paying monthly's. I can't wait for this account to be closed maybe other reasons Adgars is going down is this. Each call I get daily from Adgars I pay for including letters that don't receive.
