Terrible *********** and Poor Customer Service

I purchased a laptop from auto page in 2014 on contract, by the next year the contract was sold/given to Glocell. In trying to settle of the debt, no one was able to tell me exactly what was owing, each agent gave me different amounts, I have requested for call recording on numerous occasions, they were quick to say we'll call you back but failed mention that their turn around time was MONTHS! Eventually i managed to get a hold of a lady by the name of Vasantha, she gave me a settlement amount of R700 and some change and did a debit order. Once the debit order was done, she sent me a paid up letter this was in March 2017. I went about my business thinking my debt was settled, in the second week of September i received an email from Auto Page, this was a s129 letter of demand, thinking this email was sent in error because i have a paid up letter i ignored the email, worst mistake ever! Yesterday i received a call from Norman Bissett at the time i was unable to take the call so i called back. I spoke to a lady by the name of Aqeelahe, who informed me that i have to accounts under my name that were handed over she only gave me amounts 1 for R722 and the other for R2641, she could not give me any other information whatsoever! I would assume that Norman Bissett is a reputable debt collection firm but really to provide such vague information about an account that is in arrears for apparently 6 months? So i explained myself to the lady and sent her the paid up letter, to date i have called them on numerous occasions and no one can tell me if they received a paid up letter. A little while ago i got in contact with a lady named Cynthia from the Nimble Group, she was also unable to give me any details about the accounts and said she will get back to me. I did an ITC check and I am now listed on the ITC as a slow payer, how can you people just list me even thou i have a freaken paid up letter??? I am tired of running around just to get feedback, if only you'll could respond to queries as fast as you'll listed people you wouldn't get so many bad reviews and experiences. This review does not do justice to exactly how I feel amount the service I have received from all of the companies. Its companies like these that give call centers a bad stigma. Please be advised this is my last attempt at trying to resolve this matter, if I do not receive feedback from the relevant people by the end of the day as well as an apology I WILL GO NUCLEAR!!!
