useless service

I received a message from mweb last week monday saying my adsl line was connected a week and a half later im still waiting....ive called mwebs tech support 3 times in this period and each time i do they log a report and say they will get back to me......i was sent a bill last week stating i will have to pay from the reported time of 'activation'.....i will be puting a stop order for any payments to mweb at the bank...they were seriously fast in sending me the router and confirming the deal and even faster invoicing me a bill for a service i have not even used....i would rather at this time cancel any form of subscription and take my business elsewhere to a company who actually live up to their end and deliver
