INCORRECT CHARGES, **** TO AND NO SERVICE

I connected to Broadhost on 16/11/2015. I paid for a router and 1 month 4mbps uncapped home line in advance. I never received a 4mbps line but a 2mbps line. From 17/11 I was told via email that the line was submitted for migration to 4mbps. It has not been done. From 21/11 I have had issues with the internet where I could not connect at all for days. I sent proof that the internet does not work and the response I get is that my account is very active even though it shows no activity at all. I calculated out of 46 days with Broadhost, the service has not worked for 27 days. The sales rep said that there was a problem with the router and apparently logged a replacement call on 01/12. I have not received a replacement. I cancelled my service thereafter and my internet has not worked at all and I have already paid for the entire month. I was told that if I cancel my service they will not assist me at all. I requested a refund for the router and the days my internet has not worked and they said they will give me 'service' till mid January to compensate. But the internet does not work and they won't fix it. I want a refund for the router and all the days I did not have internet access.
