MTN took my money 😡😡

I bought a new MTN Sim card at a PEP store because I heard about MTN having a data deal of 100GB for R200. This was my very first time using MTN so I was not too sure how to purchase the data but I eventually got to the option where I could buy the data. After purchasing it, I realized that my data was still not working even though I did receive an sms that my purchase was successful. I still carried on trying to get the data to work and I kept struggling, so I decided to call customer service, the first lady that I spoke to knew nothing that I was speaking of, when I called the next day, the lady I spoke to just told me "you migrated to another plan and your data has been forfeited so there's nothing I can do". I feel that is very unfair because that is literally a whole R200 that I lost just because I couldn't understand how to navigate the whole process. No one even went the extra mile to help me get something back from the money that I had lost. I am very unhappy with the service that I received and would never recommend MTN to anyone because of this absurdity😡😡😡
