POOR SERVICE FROM VODACOM FIBRE

Since last week wednesday we havent had Wifi. we phoned them to log a query, and was told that our system was pending for an upgrading from a 20meg line, to a 100meg line. so they lady tried to assist to get the wifi connected again. they line cut off, she hasnt phoned back. we phoned thursday again, same problem. friday, saturday and sunday we phoned, logged queries each time, and till today we havent had a response back from Vodacom Fibre. no one can assist us by getting us back connected, and no one can tell us about the approval of upgrading the line. not me or my husband spoke to Vodacom to approve this. and no one is getting back to us. its been a week now without wifi, im suppose to work from home, but with no wifi, i have to go into the office. im not happy with the poor service Vodacom fibre is supplying, and im wanting a credit for the week without wifi.
