Failure to remedy

I have had an ongoing problem with Vodacom Fibre

They installed a router it never worked and after 3 weeks of ongoing calls and over 50 emails still no resolution. The numerous service requests were simply never followed through . They then collected the router which had never worked and billed me ( no invoice) I requested a copy which never came , but because I had been promised a credit to my account I did not worry . They have now billed me again .

The problem is one department simply says They have passed things on .

Come on get your act together
