MTN service not existing

My husband passed away in December. He had a MTN account. Beginning of this year, I tried to cancel the contract. The lady, Dineo, at MTN Newmarket, told me I had to do a transfer of ownership. At no point did she tell me I can just cancel the account. Since then I have been trying to reduce the contract because I cannot pay the almost R2000 business account my husband had, and I am not using the phone. ***) I have been to the branches, I have phoned customer services, I have emailed, and I get NO response. Last week someone emailed me a migration form, which I completed, and since then, NOTHING. I have been paying almost R2000 for the last 8 months and it is money down the drain. I will never ever recommend MTN to anyone.
