BAD service and WORSE customer relations.... Disappointed

I thought this was a good company but my thoughts has changed very quick. I was contacted early during the year of 2018 by Kelly Prins @ 14: 28 on the 4/7/2018. She advised that DC experts consolidate and worked out everything and said my term is for 2 years. Sounded to good to be true and I said first confirm if it is true and then I'll do it. She confirmed, worked out all details and said I must just complete the documents they send and they will stop my debit orders and they have already notified the creditors which was just awaiting my documents. They sent me a fixed amount and said everything was confirmed and successful. They sent me a sms to advise Carol is my counselor, all good. Then it was past the 2 years, I never received a call from Carol or anyone at DC experts, thinking everything was going good on my portfolio. Then the supposed 2 year period was done and I called their offices, just for an update to when the debit order will be done. Carol advised me it will still take time as something was not right, I said ok and she confirmed she will call me back that day.. I thought leave it for another week and no one called, so u called back to their office. Carol told me that one of the creditors did not accept, this is after more than 2 years , is it ok they going to up my amount of the debit order. I advised her, that is not on as I have signed the agreement and someone needs to take ownership for this mistake, as I done everything asked from myself. Carol advised she will forward to the accounts department and they will check, the next month my account increased almost by R30000 and I did not hear from Carol, everytime I called she was on lunch or leave or she is going to call me, to date nothing. Then I got more people who confirm they would assist, Vialante Vass, Ashleen Prag and Phathiswa Makaluza. Vialante advised me she was working with Carol as my accounts was increasing and I am not meant to pay the extra funds, of which I have the emails. Since December 2020 no one has given me feedback and no complaints department, they advise I can't speak to management, not to account's and Carol does not come back. I called again in 2021, Vialante has apparently resigned and no one else one is doing anything. In almost 3 years my account has not come down, not even a quarter of it. I have been nice for a long time, I need someone to sort this and put fire under someone as this is not right the way you are not giving good customer service, it is pathetic as I am paying for someone else's mistake. One account that was almost completed is in arrears, with all my debt for years have I ever let one go in arrears and here you are making my name bad and worse than ever
