Telekom, Umhlanga, the crescent swindling ******!

I went to buy R99 worth of data on the 9th of January 2021. I was supposed to receive 5+5 Gigs. To my disappointment I realized that my receipt was done offline.. So I didn't have any data uploaded. I could not wait till the following day to sort this out. I then purchased 10+10 Gigs on my banking app which I received right away so I could work. Today i.e my sister went to the store to try and sort this out. My sister was not aware that I had also bought another 10+10 gig. They told her that if she has shopping to do he can go and come back later to give them time to upload the sale. She went to Pick nPay and came back later. The sales person told her that the data was uploaded and that I had already used 3gigs. When she asked how can that be because the sale had just been activated, they could not give a satisfying response She came back and relayed the news to me. I got angry and has been calling the shop since then. I'm attended by an answering machine. I have pressed all the options but none of them is attended. I have been put on hold for all of the options. The tellers there are ****** straight I wish Telekom cam intervene and give me my hard earned money back.
