Continuous mess ups with wireless

So I have been a Vodacom customer for years and have had very few complaints generally, which is why I was so disappointed when I tried to help my mom with her wireless device which she got from them.<br> <br> She brought the device and spent weeks trying to get it to work, the Vodacom employee apparently promised her she could just plug in and go! Eventually I tried to fix it and it was clearly not functional. The call centre descovered she had been given a sim card registered to someone else altogether. She went back to vodacom and explained and they gave her a new sim and cancelled the old one...only...they infact cancelled and replaced her CELL sim and not the wireless one so her phone died until we figured out what had been done. She went back again with her laptop and the guy was unable to get her laptopn to connect and said there was a problem with the laptop itself. She had to spend R700 getting someone to \fix it"and he assured her vodacom should have been able to do what he did. At this point she has paid for 3 months of data which has just gone out the window"
