VERY BAD INTERNET SERVICE

We say in Pearly Beach, we have 4 Vodacom account, the two data contacts is useless because there is hardly any service, the line connect and then it cannot reach any site, what is the use of having 15 gig data contacts and no service, One cannot cancel the contract to go to a nother service provider, so you are stuck with Vodacom. The 082111 number is useless, I do not want to complain about a certain number, I want to complain about the internet connections, so you sit for hours on the line listen to nonsense, without any help. It is now 4 days that the line connect very slow, but that is the last, from there it cannot reach any site... I am sick of Vodacom who is selling contracts which they cannot service
