Worse service provider ever

This is the worst ever service provider. I have waited 4 months for the installation on my adsl. The first bill I get is dated to middel of june that is a 2 month bill on the first one. They sespended my service that you can't phone them. Were is the deal I signed for. I did not even get the month free they said I will get and I had to pay for the router and extender that were sepose to be free.
