SSDA debt collectors does not reply

<p>MTN handed me over to SSDA debt collectors because I stopped my debit order after they overcharged me and never responded on my complaints/logs. I felt that MTN breached the contract and never bothered to sort this out with me.</p> <p>SSDA harrasses me with mails claiming more and more : R3950, then R4041, then R4149, then R4204 but small sms claim of R177. Why the difference ? I reply on each mail they send me, but they also never respond, except for increased accounts they sent.</p> <p>I need them to respond on my mails I sent them. I cannot just pay if I feel I was the victim at MTN.</p> <p> </p>
