Extremely bad service and not providing what I have paid for

I logged on to myvodacom to buy some data in Dec. The screen kept freezing and the purchase did not look like it went through. I did not get a confirmation from Vodacom or from my bank to confirm a purchase was made. Next day I see that 3 amounts of R549 were taken out of my account as payment to Vodacom but only one lot of data was added to my number. I called Vodacom who said I must call my bank which I did. My bank said that it is for Vodacom to resolve as I purchased the data on myvodacom. After a few more calls getting nowhere I contact vodacom again who asked me to email the proof from the bank that 3 payments went through to them. I did and received a response saying I would hear from them in 24 hours. Of course I didn't. 3 days later I email them again and a lady rep**** to say I must contact my bank. Seriously! So Vodacom say I must contact my bank and my bank say Vodacom must sort it. I have mad a purchase directly to Vodacom Have now sent them my bank statement. They now have my money but I do not have all the data for that money. Vodacom, your service is beyond bad. I have no faith in you to resolve anything right now. I have 5 business numbers with Vodacom and will look to move them all to another provider when I can as I am disgusted by your lack of customer service.
