MTN Insurance Complaint

I had my phone ****** a few weeks ago and I thought to myself "Luckily I have insurance on my phone"....

I phoned the Mtn insurance number after blacklisting the ****** phone and opening a case just to find out that I've been paying insurance on a phone I had 6 years ago. None of my other two phones that I signed a document @MTN for insurance are insured. I was told by the insurance lady that I had to phone in to change the insurance to the new phones when I upgraded. None of this was told when signing for the insurance. Now I'm sitting without a phone and paying insurance on a phone I had 6 years ago.

Really disappointed with MTN.
