Overdue vodabucks

On Monday morning on the App I activated the goal for "Just 4 You data bundle" the information contained was"get 100 vodabucks when you purchase a Just 4 You data bundle for R20 or more before 06/03/2022" , the information also appeared on via USSD string. I immediately purchased a Just 4 You data bundle for R23 giving 175mb daily for five days. The problem became when Vodacom failed to deliver on its promise, I contacted their call centre,a consultant provided me with her email address (Matete.Ramaoka@*****.com) in order to send her a screenshot as proof of the offer, which I did, however she never rep****,last night I contacted the call centre again and I was never assisted. I explained the problem in detail and about the email I sent but still no assistance,May someone professional please attend to the problem, hence I indicated to the consultant that every week the"just 4 You data bundle" gives me problems in terms of allocating the vodabucks Other problem is my sim card has an issue when coming to extra airtime.
