No internet/data usage

I received my phone back after i booked it for repair, costed me R2000 (for a new screen)<br> They gave it back and i could sms and call but couldn't connect to the internet.<br> They had a look and couldn't get it fixed,<br> they now want to book my phone in and do a factory reset? But why is this necessary on a screen repair?<br> I even did a sim swap and the same issue is occurring, i think vodacom does this to their customers to get them to upgrade, and there is now way i am going to now, i had a contract, paid on time every month for 24 months. I am deeply disappointed to pay R 2000 to get my Samsung back even worse than it was before i booked it in. Now ontop of all of this I have to spend even more to get to the branch (for the 4th time now). I also have 1GB of data, that will expire at the end of this month, that i will not even be able to use even if I wanted to. I want a refund, as this is ****************.
