Mis Selling Security Contracts

I have called into the contact Centre on Numerous occasions (8 Calls) have given endless complaints for bad service and to get my issue resolved. <br> I have been promised call backs, resolution and nothing has changed my circumstances and my query is still unresolved. <br> I was approached by a sales representative from Chubb and advised if I switch from ADT, they will fix my contract at R260.00 for 36 months. After the first 12 months I noticed my bill had increased from R260.00 to R289.00. This is when I contacted Chubb and advised of the increased amount to my bill and the rude consultant in Admin Department advised me this error is impossible and all customers are subject to annual increase. This is when I told her I requested the sales agent to list the fixed payments for 36 months on my signed contract. She told me she would need to find my contract first and 2 months later, with 7 calls later my issue is not yet resolved.<br> I was told each time I called it would be investigated and someone would get back to me and still no one has gotten back to me.<br> If this is how Chubb treats their customers I will not recommend anyone go with Chubb. They have mis sold me their service.
