MTN so good as misleading and causing finanical pain

Wow MTN, you really found a way to take money from your customers. I signed up for a 20G sim data package with the device for R 230.00 a month and now my monthly account has gone from almost R 900.00 (Cellphone and sim contract) to almost R 2 000.00. When the usage document is send to me it shows that there is R 0.00 amount outstanding so of course then according to this there is no issues but wow when the debit goes off, different story and then the new usage document shows something complete different. Data is being loaded that I did not request. I took a package deal that is suppose to be capped at 20G but MTN seems to just be loading data and sending me documents that misleads so that it's to late to query it. Is this how Rob Shuter runs MTN? Loading data through ***** ways that I didn't authorise and didn't sign up for and conveniently nobody in the call centre to assist. Wow Wow, do you not think if I hand the money to pay R 2 000.00 grand on data that I would just install the best fibre line. No, I trusted MTN and took a package that I could afford according to my Budget. I am so disappointed and upset. My money is being taken and I can't seem to stop it. I want this matter attended to, I want the money that was taken from be given back. I will take this further if this is not resolved. I will not continue my business with MTN for future. When my contracts are done I will go to a different service provider. Been with MTN for over 10 years just to be mislead and taken advantage off.
