Bad Service: Fibre Activation

I signed up with MWEB on the 27th May 2020. I informed them that my Fibre contract expires on 31 May 2020 and provided them with my routers FSAN number. i have been waiting for my internet activation since then, even after telling them that i have a complete installation. I am still being treated as if I need a new installation - they even had an installer calling me though I had reported on numerous times that I do not need a new installation.
