Vodacom Masterpass is a master fail

On 11/01/2021 I purchased R100 airtime from the MyVodacom app for my husband. The money went off my bank account immediately, but I have yet to receive the airtime. After many unsuccessful attempts at complaining (they are very user unfriendly in that you just get machines to converse with). I eventually phone 082135 and spoke to (at that stage), very helpful young man called Shadrack Tsotetsi. I received his e-mail address and sent all the relevant info, with screenshots and proof every time he asked. Now he has stopped replying to my mails and I am still out of pocket without receiving the airtime.
