MTN took my money and did not provide the service!

Almost 5 months ago, I bought R99 airtime/data by card, using their app on my phone. The monies were deducted from my account, but no airtime/data was received. After giving them 24 hours grace, I emailed MTN to report the problem. Weeks later, they notified me that the card transaction had not gone through on their side and I should contact my bank. My bank informed me that the payment had indeed gone through and I could no longer reverse the transaction as too much time had passed. I went back to MTN with the issue, they asked for a copy of my bank statement showing the transaction, I provided it. No reply .... I emailed again ... two weeks later I received a reply that they will look into the problem ... then nothing, I emailed again .... again weeks later, promise to look into it and get back to me in 3-5 business days ... I received no feedback! After waiting a few weeks, I emailed again asking for a contact number and for the problem to be escalated .... no reply, resent my request .... finally an answer? No, just another reference number and promise to look into the matter ... and nothing received since then!
