Bad Customer Service

I'm so disappointed with the level of service I got from. Vodacom.Although it wasn't for a big amount,and maybe that's why it wasn't taken serious but with the last money I had in my bank account ,I bought myself the R29 1gb per day for 3days promo data bundle on vodapay zero using my bank card.I urgently needed to use that data for job application submission amongst other things ,but I didn't get it but the funds were deducted from my account.I enquired through the vodapay 24hr support chat box and was told it will take up to 48 hours.As I'm writing this it's almost 48hours and when I enquired again I was told that the people it was assigned to might have a backlog,it might take up to 7days n that they don't work on weekends.Do u understand that I might've missed out on a huge opportunity because of 1,Vodacom's technical failure and 2.failure to resolve issues within the given time frame.I am utterly disappointed and very angry.
