ISP Reviews by TheTechGuy

I've been with this appalling excuse of a company for 9 months.

In that time I've had to call them, I kid you not! over 20 times, emailed them over 200 times, had 4 engineers out to 'fix' a problem which they are clearly so incompetent at.

One member of staff said "I understand you're having all these problems but it's not really classed as a problem"
I was offered £5 compensation as a result of my on-going issues with them!

How this company is still going I don't know.

They are the worse performing telecoms/broadband company in the UK.
(Some articles span over the past 2 years however, still applicable to date)
