Incompitence

After having to wait for over a month for my insurance claim to be processed, I now have to wait even longer because the person processing my claim processed the incorrect amount for the value of my cell phone. These people debit my account every month and never make a mistake of the value of the contract. I've been without a phone and my sim card for way longer than I should have and no one even calls to apologise for the inconvenience. I work of my phone and have had to get clients to get me on different numbers all because MTN didn't fulfil their contractual obligations to me. ref: #***4
