Bad service

RSA WEB are the worst service providers there are out there. I logged a ticket on the 5th of February because my internet was down, they told me it would take 24 to 48 hours to resolve my issue but till today nothing has been done. No feedback has been given to me and everytime I call in all the call centre agents can do is ask me to reset my fibre box. I've spoken to more then 10 different call centre agent and all I get is " we will escalate the matter" but till today no one has contacted me with a solution to my problem. I've had to get someone private to come and check what is wrong and was told that the router is the problem, when I explain that to them they say the will escalate. Clearly no one there knows anything, I've lost a whole week of business and no one can give me answers.
