Pinnacle Marketing *****

I am insured with Pinnacle Marketing for my devices through MTN SA. I recently lodged a claim for my phone that got lost. However my claim was rejected, with reason that my 3 devices that i have insured have not been using numbers that they are insured with, which is UTTER NONSENSE and a lie. The device that i lost got lost with the sim card/number that i had insured it. I had been using that number in that phone from day 1 til the phone got lost and have never used any other number. When i asked that the cellphone usage be tracked, the call centre agent (Nombulelo) tells me her system is off line, how convenient!!! When i asked to speak to a supervisor, none is available as they are ALL in meetings. I refuse to accept this reasoning cos i am 100% certain its a lie. I am aware and have been getting communication on that Pinnacle Marketing's contract with MTN SA comes to an end at the end of October 2019. Is this a way of running away from paying out valid claims ? I have not been paying insurance diligently for my convenience, only to be cheated and **** to.
