Worse service ever

I used Voda pay app to buy essential for my grandma this past week on the 1st of September 2022, Vodacom is denaying to deliver my good they demanded that I send them my bank statement to proof that I did make a payment which I did send to them, to my surprise they just went quiet when I call them they take me from pillar to post I m even depressed and hospitalized becouse of this whole situation my grandmother as we speak she depend on neighbors for food for survival, I reported the matter to icasa, consumers protection, even human rights commission but Nan responded to my report
