WASP services and welcome calls

I recently found out that somehow, I don't have the faintest idea how, I was signed up to two WASP services which was costing me R7 each per day. So every day R14 was deducted off my account. This seems to happen regularly with Vodacom that randomly WASP services are enabled. I am meticulous at making sure I do not reply to any SMSes that I get or that I don't accept anything I don't know what it is. I am appalled. I have no idea how long these services were on. I eventually found out I can stop them on the app, but I expect a full refund for the airtime that was deducted off my account unknowingly and detailed statements to indicate the amount that was ****** from me and so I can make sure I am given the correct refund. Another gripe is welcome calls. Every month or so I am told by people phoning me that I have a welcome call on, then I have to go and switch it off again and a few weeks later it is on again. I don't know if this costs me anything but I am disgusted by this. Get your act together Vodacom this is extremely bad customer service and ****************. The Ombudsman will hear of this if I am not contacted and refunded.
