Very poor customer service !

Wanted to sign up, waited long for a call back, eventually got called and visited by a consultant, she assessed and said she would email me quotes, in the meantime I wanted to enquire about some changes and she never took my calls or called me back, over a week later she finally calls, we discuss, I email her the requests, she responds stating her manager says we must pay extra, I reapond arguing my point and that I would rather cancel, I get no response at all. I then email again and CC in the customer care with full details of why I am not happy and want to cancel signing up with them and almost week later today have had no response from them whatsoever! Now if they treat new potential clients like this I can only imagine how they treat existing clients! My brother in-law was told 7 days to install and waited over 3 weeks and from the response time I was getting I can only imagine it would take so long I too was told 7 days but yet it took 8days just to get quotes and a call back from the consultant. Very disappointed with the service and felt like I was begging to be their client yet they should be chasing me!
