Kindly reimburse my airtime.

MTN has not been of kind service lately. First I lost 6 GB in three days. It took the fourth consultant to consider data usage and switching off my background data usage. I am wondering if consultants do go for proper training. Yesterday (11/07/2019) I bought an airtime that amounts to R54.00, however the airtime hasn't reflected yet my bank shows an amount of R54.00 has been deducted. I had a balance of R30 something rands thus I highly doubt my airtime has disappeared through internet or mobile data of some sort. Kindly reimburse my airtime thank you
