MTN customer care - Trying to cancel a contract for a deceased person.

I have been trying from last year to cancel my deceased husband's contract and put the number over to prepaid. i have been to 4 MTN stores, sent various mails and phoned about 15 times.

Docs were uploaded instore and mailed.

Customer care rep**** 3 times on my mails that they need to speak to my husband after the mail clearly stated he is deceased??????????????

Mail sent: Good day team please assist with cancellation of customer contracts and move numbers over to pre paid customer is deceased

reply: Thank you for your email, we apologize for the delayed response and for any inconvenience incurred. Kindly get your husband to contact us and provide the below information for security purposes, so we can process the cancellation.

What on earth do I have to do to get assistance?
