Poor services

Purchase 1G+30mins for R15 on the 18th July, around 11pm the same day, I purchased the same bundle and the expiry date extended to the 19th July 11:59pm. I got the confirmation sms but that bundle and minutes got forfeited and never carried over. Called and spoke to Aubeki and supervisor and they gave me a **** ref no:A2-TAX0-US5UP. I'm fami**** on how to check data usage on Vodapay and my background is restricted. I'm very disappointed in your staff and services, it's just R15 but I needed that data, hence I purchased it
