DISGUSTED BY SERVICE FROM MTN

My husband passed away 4 months ago. For four months I have been trying to cancel his contract. I have a trail of evidence in the form of e-mails, in-store visits, whatsapp messages as long as my arm, and this is yet to be resolved. They have the audacity to continue to bill his account monthly considering this situation has been created because of their INCOMPETENCE. The latest is receiving a certificate of balance where he is being penalized for the balance of his contract and has to pay the cancellation fee for the remaining months - disgusting ! I decided nevertheless to pay the full amount to avoid being billed any further - guess what ? The reference no. THEY GAVE ME to use is invalid. I cannot pay the account and I guarantee the balance will have gone up again next month. NOBODY IS BOTHERING TO RESPOND. MTN you should be ashamed of yourself !!!
