Poor service

Decided to go with Webafrica. As I previously worked for one of the FNO companies I had a good feeling about webafrica. Boy was I wrong. Firstly they wanted to install a new ONT box after I stated I had one. Sorting this out was an issue by it self. Then all they had to do was activate the line, I had contact numerous times to get this sorted out. After activating the line have only had speeds of 40/10 when I am paying for a 40/40, I have asked the over and over to fix this, I have been promised over and over it will be resolved yet nothing has changed. Not being able to phone someone and having to be forced to use the whatsapp service has been frustrating and nothing but empty promises. Why am I having to pay for a service they can not provide....?
