False Advertising and Over Charging.

I had Fibre installed end of November last year after being communicated in October that they had a promotion on where it was free installation and the first month Free,Subsequintly they did not send me a statement.I only received a statement after the second month where they charged me for the first month aswell as installation,I communicated that this wasn't the promotion that i signed up for where they went through their recordings and apparently there wasn't a confirmation phone call which i did make to confirm the promotion was still on.Even worst one of their representatives communicated with me an hour before he wanted to collect the router and i communicated that i do not drive around with a router in my car!I tried to arrange a date and time for collection but yet again no communication from their side,I have send several emails regarding this but still they haven't gotten back to me.This is the worst internet provider i have dealt with, billing me for a router that they didn't want to arrange to collect aswell as charging for the installation and first month which i shouldn't have been.
