Maybe i should cancel my contract because clearly telkom does not need my business

I have a contract with Telkom Mobile and I took out cellphone insurance with the insurance company that was suggested at the post of sale (Worst Decision Ever). I was unfortunately pickpocketed on the 17th of March 2018 and when I phoned Telkom to blacklist the phone it took them 24 hrs and 4 phone calls to do it. I then followed their procedure which is reporting the phone to the police and sending the claim through to them. It has been two weeks still there is no feedback on the claim and to top it all when I phoned the call center to follow up on my claim I was told that there is nothing that can be done there is a backlog and the rude consultant cut the call on a paying customer.
