Shocking after sales service from C-Surance and Cell C

Took out a contract from them in Feb this year, the phone was lost towards the end of November.

The crazy thing is I requested insurance when signing the contract. I was assured this was in place. Their services were "offline", so they sent me an offline contract for third party insurance, this is through Hollard. I signed and returned the contract as requested.

They never activated my Cellphone insurance! I have been waiting for 3 weeks for ANY ANSWER FROM Cell C Tygervalley regarding my "claim"! More than happy to pay the owed premiums.

Their standard answer is "they are investigating" - What could they be investigating, after they did not follow through with their services? I have proof of the signed contract and that it was successfully sent through to them. I tried contacting their regional branch on the number available on the web - *** - "Number you have dialled does not exist." Any help here would be greatly appreciated. I am at a loss... Shocking service from Cell C, Cell C Tygervalley and Hollard!!!
