Telkom Insurance

I have been paying my telkom insurance for my cellphone for +-3 years now. I have recently neen told that the IMEI number on the system does not match that of my cellphone, I am not sure what happened . I have asked for it to be rectified as I cannot keep paying for something that I am not sure of. I went to.Brits mall branch even though I had done the insurance at Wonderpark branch . I.was first assisted by Muawi (not sure of the spelling), who assured me that the matter would be solved in 2 days. No communication from his side in a week and I then decided to go back to the Brits mall branch only to find that he did not do anything on the matter and he went on leave. I was then assisted by Odirile who said he will give feedback. He provided feedback only once and also decided to keep quite. I went back to the Brits mall branch and found Conry who assured me he will escalate the matter to the manager if he does not manage to solve it himself. Conry took my contact details and gave me his as a confirmation that he will provide feedback however I am the one who constantly had to ask what was happening . I am advised the matter is now with manager however it has been more than 3 weeks without hearing anything .What am I supposed to do in this situation ? If I do not get feedback within the next two days I am going to Twitter with this matter.

Your help will be highly appreciated.
