An angry customer

On the 1st of December I bpught R30 airtime twice via my bank, at that time cell c was having issues, people later got compensated with one gig of data which I never got but I dnt care about that, I need my R60 airtime which shows on my bank statement It was deducted, I have been calling and calling but im told to email some serial voucher number of which how I will get that is still a dilema to me since I bought the airtime via cell phone banking.

Im no longer in need of this airtime as u have failed to load it the time I needed it, now I.want my R60 back to.my account thank you very much
