Vodacom support broke my WiFi

Got hold of Vodacom support since my uncapped LTE WiFi was a bit a slow, they responded that they "synced" my line and ever since I have not had WiFi later I called another support line and they told me that they don't "sync" the LTE lines and whoever did that broke my account.. Now they have advised us to take in the whole router to a Vodacom repair shop and this is a huge inconvenience as we are about 2 hours from the nearest town with a Vodacom shop.. and we have already paid for this month's WiFi so when I requested that perhaps they could add data for the time being as when the support team couldn't fix it they added some data to it and that seemed to work at least for the time being. They refuse to add more as they have already added 10 gigs to it and can not possibly add more.. you would think anything is possible when dealing with a paying customer. The worst part is it's a 3 year contract.
