Capitec airtime

I loaded R170 airtime on my phone via the Capitec app. on the 23rd July at 11h02. My Phone was however not loaded with the MTN airtime. I called as soon as I realised at 11h26. I was told that it should be loaded within the next 48 hours and if not they would reimburse me. I called again about a week later to enquire, still no airtime or reimbur*****t. It is now 6 weeks later and nothing has been done, despite query it twice telephonically. Pls advise why I need to waste now more airtime, just to call the bank again and again with still no resolution.
