Misadministration and non-existent ************* customer services

Non existent customer service. I am Client of King Price Insurance who receives a discounted monthly fee for the Beame tracking unit installed. Mix Telematics contacted me after receiving my details from my insurer. They do not apply this discount and never respond to any calls or e-mails. The Contract lapsed after 3 years after which they continued to charge me R 155.00 a month (as opposed to the R 59 a month), in an effort to make this stop I submitted a notice of cancellation to them which was ignored and never confirmed the cancellation under e-mail. I had no choice other than to notify the bank to reverse the unauthorised amount. After receiving a call from one of the debtors he got angry with me and continued to drop the call. After multiple e-mails setting out the situation they hand you over to a debt collector's agency the credit bureaus non the less. The debt collector agency also do not respond to any emails and allocate a different person who has no knowledge or record of anything. Totally ************* service with nobody responding to any e-mails whatsoever, despite being allocated reference/case numbers for the e-mails sent.
