The worse service ever....

Horrific Customer Service experience.... can you get worse than this. In August 2017 exactly a year ago my mom took out a contract bundle deal with Cell C. The devices was really bad quality and it kept breaking so after two replacements they said they would cancel the deal and offered to give my mom another bundle with Samsung phones for the same price. She agreed and the Sales person Marius ( N1 City Goodwood) came to her door to sign the contract. My mom just had a eye operation and she asked all the questions and was Marius confirmed that the contract is the same price she said she can’t afford more he assured her everything was the same it was a better deal. Mom then started noticing that the amount being debited was different to the agreed amount she went into the N1 City branch and they kept telling her they will fix it. In January of this year she was still going up and down each month to get it sorted when they debited R920. The next month they debit R1600 and R1700 . Her entire salary by the way. Each time she went in she received the same response, we are waiting for head office. Then she spoke to the Manager, he kept explaining that he was new I’m not sure how that makes a difference when she explained her story he was just as bad as his staff and when my mom spoke Afrikaans to this Marius guy he played th race card pathetic... My mom went in to Cell C every month the past year and she still has no resolution. She then was told by one of the staff that there was 4 contracts on her name so they failed to cancel the previous contract and if you think that’s bad, Marius deceived my innocent sick mother and made her sign two separate contracts. You tell me why your staff has to resort to this type of dishonest behavior and the manager can’t even do anything. My mom has given back all theses devices and we want this contacts canceled and all this amounts needs to be written off as she can’t be expected to pay for something she doesn’t have. If this matter is not resolved in the next 7 days I will makes sure it’s put all over the media and social media and I will log a formal complaint with the telecommunications ombudsman.
