MTN Horrible customer care service

I bought airtime on the 28th of July 2024 using extra time, the data was 1.5 G within 15 minutes the data disappeared. I recharged again and bought 2.5G 15 minutes later the data also disappeared. I called MTN call centre to report this and I was told that they will investigate the matter because it shows that the data disappeared but they don’t know how. The agent said she will ask her supervisor to do investigate the matter and after reimburse me. I have never received feedback and I have been following up and every time I call for follow up I am given a different story. Today the 21st of August 2024 I call and I spoke to Ntshovelo Ndlovu and she gave me a different story and said she is getting a supervisor for me I must hold. I was put on hold for about 5 minutes and she came back and said she got a supervisor then when she was transferring my call the supervisor didn’t answer the phone it went straight to voice mail. Almost a month later MTN is not able to solve my matter and not taking responsibility of what happened.

This has been frustrating till today and they don’t seem to care about my matter or take me serious. My ref no of the matter is SMC***. A very horrible service from MTN
