Billed, yet never received data and airtime I purchased

I'm being reaped off! I bought R50mtn airtime on the 1St May 2018, via my rcs app, I never received the airtime, yet my account was billed. On the 28th May I bought mtn data bundles of R160, I never received the data bundles. I called the call centre on the 29th of May in the morning, and I spoke to an agent by the name of Phelo, who confirmed that these purchases, show as pending on their side, yet I told her that my account has already been billed. She promised to track my account and get this sorted within 48 hours, well she never called me back. Now today I bought another R160 worth of mtn data bundles, and they are not credited to my account. I'm really frustrated now, because even if I call the RCS call centre I'm adament, that I'll be **** to.

RCS, I want my data and airtime, for the payments have went through, if this is not sorted by close of business today, I'll have to escalate to to the ombudsman.
