Unprofessional and pathetic services

I have 4 contracts with Vodacom. On Friday, 9 Feb, I try to buy data for my ****le on the app and website without success. I called Vodacom on Monday, 12 Feb. The lady insisted my app is out of date and finally understand after 20 min that the app is unistalled and re-installed and even the website doesn't work. Services request logged. On Wednesday, 14 Feb I've called again and they load data from their side (so I didn't received the double data). On 12 Feb I submit a complaint on Hello Peter with Vodacom replying they will contact me. Still waiting for that call and it is 18 Feb already. On 15 Feb I buy double data for my cell number and never received the double data. I called Vodacom on 16 Feb. The lady just told me she don't see the purchase although I have the email to proof it and the issue on the other number is solved according to her. So once again no help from Vodacom. On 18 Feb I call Vodacom again because I had to buy data yet again because of their pathetic service and the lady just told me the fault is on my side although I've done exactly everything Vodacom told me to do. I week later and nothing is resolve from Vodacom's side. This is not the first time I have this trouble with Vodacom. Needless to say, I won't be renewing any of my contracts with Vodacom
