Unhappy wit MRP mobile

I am not happy at all I received a sim card for being a loyal customer I activated it in mid July and received the airtime of R75 as agreed I then bought a R49 1 gb data bundle and it showed the purchase as successful but when checking the money was deducted but I didn't receive the data. When phoning today I was informed that there was data issues but not that I would be refunded also the R22 that was supposed to be left was gone and I show a balance of R0. 07 in the minus only to be informed that this will be deducted with my next airtime load. I then asked that this contract must be cancelled due to no assistance and issues from day one then only to be told I have to pay R350 to cancel. I then asked to speak to the manager or supervisor and was told they are busy on a call and will phone me back. I told them if I don't receive a call by cob I am reporting them on Hello Peter. This is unacceptable and unprofessional it gives MRP a bad name. If my issues don't get resolved I will take this further on social media I am really not happy the consultant she had a bad attitude and was not assisting in any way. Pls contact me ASAP Natalie
