MTN - NO SYMPATHY

I would like to share my disappointment with MTN South Africa. I've been a very loyal customer with the same number for longer than 20 years. I took out a contract for my twin sister who in turn paid me back for the contract. I've updated both our contacts in December 2018. Sadly she passed away in January this year which means I've lost her income. MTN retentions are telling me staight there is nothing they can do for me. If I want to cancel her contract I need to pay R10000, money that I really don't have.. As things are really tough financially. I had to cancel most of my policies etc to make ends meet.. I do realize I've signed a contract and I'm not saying that I will stop paying completely, all I'm asking is to help me to bring down the amount of the contract and extent it if they have to. REALLY REALLY DISAPPOINTED..
