joining telkom is big mistake!!!!

About 2 hears ago I took up a contact with Telkom and got my devices which I was happy with in April 2018 my car was broken into and my devices were ****** alone with other stuff, so I opened up a case with the police as well as I contacted Telkom and informed then of what has happened and got the devices blacklisted I also stated to them when I took up my contract I requested my devices be insured the agent I spoke to stated yes your devices are insured with a small fee so I ended up stopping my Direct debit as I was under the impression Telkom had taken care of everything only to find out in September 2019 when I did a credit check that my Telkom account is with they collections team and they have listed me a default on transunion ... I contacted Telkom on numerous occasions trying to get this resolved in the past week with no joy speaking to they contact centre as well as they branch in gateway Durban which is a nightmare!!! I would like someone from they complaints team to contact me before 9 am or after 7 pm on weekdays and anytime on weekends due to work reasons. to get this resolved. my contact number is ***
