MTN just as useless.......

Because I am unemployed I have a cellphone contract on my husbands name with MTN. We transferred from Vodacom to MTN in April 2018 in the hope that we will experience better customer care which in the end didn't really make any difference what so ever in fact I think I am worse off. Since April we are receiving bills that are more than 50% under the contract price we opted for. In avoiding there being a massive lump sum being deducted from my husbands account when they realise their mistake we decided to contact them and explain the matter. We were asked by a Jacob Rameetse to please email him a copy of the contract which we did June. We haven't heard from him since, we keep emailing him and there is no response what so ever! Every time I phone to ask about the matter I get told I am not the account holder and there for won't be able to assist me any further. My husband is extremely busy and don't have time to speak to 100 different people and explain the problem over and over again!! This is just useless!!
