Harassing by Daly Credit

I’m totally fed up with this company! Constant harassing of telephone calls for an ABSA credit card account for which I had an disability claim and which was excepted by ABSA. I was very surprised when the calls started which ended up in a daily harassment of up to 9 calls each day 6 days a week. I got a letter from ABSA informing me that my claim was excepted. This was the last communication I have received from them. Now I'm being harassed daily with phone calls from Daly Corp who also does not respond to emails sent to them! So it’s a like a tennis match trying to sort this out! And no one can explain where the amount they requesting is coming from! Somewhere along the line there's communication problems! It’s so frustrating they're quick to harass you but no one can explain anything to you! I have sent them several emails but I don’t get any response them! I’m currently refusing to communicate via phone due to the harassment and I have no proof for what is being said! I also receive a lot of sms's from them requesting payment and say if amount paid to ignore the email but the constantly Harassment continues. I have also being contacted by a second company for the so called outstanding debt. I don’t know how can a company like this makes use of a company like this
