Cell phone insurance claim

JET cellphone insurance has been nothing but a nightmare... I bought my phone around July last 2017 and this year around June I was ******, I had insured my phone with them the time I bought it but when it came to me claiming they told me I needed to have a second IMEI number for the 2nd sim slot since the phone is dual sim which they failed to put in writing on the insurance forms and I went to jet to request the information since the insurance forms I had only have one IMEI number but they referred me to their finride call center. I called them and they said I needed a letter from MTN to prove that the second sim slot was not in use, I called mtn and they referred me to the nearest branch but when I got to the Mtn Tygervalley center I spoke to a lady called Nono she advised me their system was offline and she would send the required letter via email but she never did. I went there again spoke to the manager Ssuzet she said she had no idea what I was talking about, she went on to tell me the number I'm claiming was mine had been re-issued in October to someone else therefore there was nothing showing on the system, so she was unable to assist me.... I called Edcon again to request a reference number for my claim but the lady I spoke to Naajida said she can't assist me but failed to give me a reason as to why.... I have been going around in circles not getting any help, and what's worse is that the insurance is still deducting from my account every month and it's been over 6 months now since I made the claim and still I am not assisted.
