Money deducted from my Capitec account, but airtime never credited to me

I recently opened an account with Capitec, having heard great things about them. On Thursday 22 October 2020, I wanted to purchase airtime for myself using Capitec's mobile app. I made myself a beneficiary on the app, so as to buy Vodacom airtime for myself. I bought R29 Vodacom airtime which was deducted from my Capitec Savings account, however, the airtime did not reflect in my balance. I tried calling Capitec's customer service to report the issue, but after holding for so long, decided to hang up. I proceeded to make contact with Capitec on the What's App line and reported the issue, however, I have had no response whatsoever. I also sent Capitec an email, but have not received a response. It's highly disturbing that money has been deducted from my Capitec account whilst the airtime was never credited to me. This is nothing short of *******. I would appreciate Capitec getting in touch with me to resolve the issue. My history on Capitec's mobile app is showing that R29 was purchased & deducted from my account however, the airtime was never actually credited to me!
