DISGUSTING SERVICE FROM VODACOM FIBRE-DONT USE THEM

For the past few months, my fiber line with vodacom has given us issues on a daily basis. we lose signal for hours every day!!!!! we have logged several calls and spent a huge amount of money on calling and following up. no one responds, managers don't call back, they promise the call has been escalated but they close the call logged without speaking to us, checking the line, or finding out what's wrong. once a technician came through and he said the router is the problem and they will replace it. I have logged calls as it is affecting my business and work but Vodacom does not care!!!! I NEED THE ROUTER TO BE REPLACED!!! I don't know what else to do!!!! but I cannot go on like this!!!!!
