Cell C and Worldwide Advisory Service insurance are *****s

On the 23rd of March 2023 I got another contract under my contract. I made sure that I would get my phone insured as well as the new one (this could be proved with so many recordings after calling numerous times to resolve) Here we are in November when the phone I got in March is lost/****** in an bolt ride. I follow all processes and procedures required by CellC, only to find out that the phone is not covered as the contract ended on the 28th of March 2023. When I go to the store or call Cell C customer care I hear stories that both phones are covered by insurance. When I speak to Worldwide Advisory Services they tell me the contract ended and that I need to pay back the billing amount from March to November, which is strange because I DID NOT CANCEL THE INSURANCE. Cell or Worldwide Advisory Service both tell me I need to contact the other because none of them have proof/evidence of who cancelled and why. What kind of professional services is this when none of you can provide me proof?
