Refund me

I have been waiting since friday 29th for a refund of R99 cause the app doesnt work as usual. They told me 24hrs ill have my refund. Sunday called again same story it will be done today if not by monday latest. Tuesday same story promised it would be done by Thursday. Guess what, its not done when incalled this evening i get told its in progress no idea when it will be done depends on there work load, it seems they must have a lot of complaints tonbe so overworked. Not to mention they say they dont work weekends nor public holidays and finnish at 17h00 in the week. And the work load is too much. How come u cant get it right vodacom, from call centre to the app thay cant count data . I hope my refund is done tomorrow before the weekend other wise it will only be next week if the work load os not too much.
