MTN Insurance - Delaying on Processing Claims

I'm appalled at the service I've received from MTN Insurance! <br> I sent through a claim for water damage on my phone on 20 February. Two weeks later I received a response that my claim would be attended to in 5 working days but that there was a delay due to a high volume of claims. On the 20th March, I received a random one-liner asking for the \correct imei number"...which had been correctly written on the claim form"
