Refusal to cancel a diseased acccount

My dad passed away in August 2017 and MTN has continuously failed to cancel his cellphone contract.

I have on numerous occasions submitted the necessary documents to no avail.

I am shocked at how insensitive they can be, as if it is not difficult enough to deal with loss now they create an administrative nightmare as well. On top of the fact that they are still making us pay (even though the phone has been off for months and we notified them multiple times, submitted death certificate etc).

This is unacceptable MTN! Please cancel his contract and reimburse us.
