Double standards and Staff are ***********!

I booked and paid for a holiday with STA travel but because of Covid was unable to go. STA travel has since liquidated and I formally requested a chargeback through Standard Bank and was shoved from pillar to post as your staff don't even know what a chargeback is! Despite your newspaper article which clearly states "Standard Bank confirms customers be given the option of card chargeback" dated 2 April 2020. Furthermore I supp**** an ABTA letter which further confirms that Master and Visa cardholders are granted 540 days from transaction date (all banks subscribe to the Visa/Mastercard scheme rules). Which makes me even more livid is the fact that several Standard Bank customers in the same boat as myself have been refunded and granted their chargebacks. How is it possible that there are double standards with this. This is unacceptable! Furthermore, after visiting your branch in Centurion on various occasions, your staff are *********** and do not know what a chargeback is, wasting my time. I submitted all the info required for the chargeback including, flight itinerary, proof of payment, ABTA letter, Newspaper article. Hopefully this formal complaint reaches the right department who actually knows what is going on. Should I not receive my refund like all the other Standard bank STA travel customers, I will bring the matter forward to the Banking Ombud and Standard bank can then explain how the other customers were refunded and not me.
