MWEB is *****ing from me.

I app**** for a fibre via Mweb, think that their service levels were better than my original service provider. They took over 3 weeks to install the fibre from their promise of 2 weeks. The service technician (cable jointer) mentioned there will issues with the fibre , and they need to get a fault finder out to look at the problem, who arrived a week later. The technician said that the fibre is activated, and Mweb would contact me for the setup. While I still had the ADsl line available, I still waited for them to contact me, still no contact. I then recieved an invoice for this weeks of non usage (still no fibre), both the user names and password sent to me do not work, when I tried to login. I trusted MWEB to provide better service than their competitors, but they are just the same. I still have no fibre, but still am getting invoiced. I am not paying for this and will put a stop on my debit order and seek legal recourse. You cannot charge me for a service you are not rendering. I spoke to Sameer at Mweb, apparently they will not reverse the costs which is *****ing.
