Airtime Complaint

I have bought airtime on the 17th Of December 2020 I was not credited with my Airtime since then. I called Capitec and I went to the Branch a number of times and all they tell is to wait for 24 hours which I did but still airtime is not credited to my account. Last week Thursday they told my account was credited with the Airtime, yet there was no Airtime in my account. Still today nothing. All I want now is My R150 back to my account. Thank you.
