Harassment from discovery and their call center

I am very unhappy how discovery is treating their clients This is really absurd and they call me monthly and I made an arrangement for paying R1500 pm into my credit card facility ,it was ignored and got 100 calls a day. I made another arrangement again saying they cant see anything under my name and I asked for those recorded calls with no luck Then they debited R2000 instead of R1500 I didn't say anything although that was not the agreement. I still get calls daily despite the debit order running ,now again they cant see the arrangement What do they want from the clients with your rude call center people This is the worst bank ever, the behaviour is pathetic

I cant be talking about the same thing daily ,I'm at work, i have to listen to the same pathetic story daily,I made an arrangement what more do you want This is nonsense I want all the recordings of all the calls and they must just stop calling and harassing me
