Cannot purchase data

Well its happened again, firstly I could not purchase data on Saturday night 20 Feb 2016, phoned in the call center on Sunday morning and apparently my number was moved to another system. He said that it can take between 1 and 48 hours, looks like had the 48 hour deal. I finally got to purchase data this morning and what happens? It does not reflect on my account. Thank you for messing up again I cannot wait for this **** contract to expire seems like they don't care and don't want me to buy data. Thanks to Vodacom I have my data off for 2 days because and ill get killed with out of bundle data rates. Maybe that's their plan, cant buy bundle data so charge you out of bundle rates whatever it is I am thick of it and will advise everyone I know to not renew their contracts.
