Pathetic service

Worse service ever. From 1 December, my Vodacom data just disappear. 800mb is gone in 5 minutes. I bought 2gb, it also disappear in 5 min. My wifi router have 20GB, it disappear in 30 min. Normally I can’t even use all my data. This month, I have none, after I decline a Vodacom offer, for extra data, a laptop and wifi router. I phoned then, without success. They send me to the nearest shop, they log a call, went for a 2nd time to the shop, another call, and still no response. They check my phone, and nothing is one, that can use extra data. Vodacom is pathetic, will not recommend them. Will also change to another service provider. It seems that they will not give my ****** data back, and if I buy they will also ***** it.
