Any excuse to reject a claim

My claim was finally looked at only for it to be rejected based on false accusation that the SIM card was not in the phone at the time of the damage. There was no evidence to back up their rejection of the claim. I have had to then chase MTN around for an itemised billing which is not part of my contract package with them so they have no obligation to provide it, just to prove that my phone was in use with the correct SIM card on the date day of the damage and everyday before and after then! Do your research before trying to swindle paying customers out of their money and honor the service you claim to provide!
