I'm really surprised by Gruntintunz' post. I am a VERY new customer of this ISP, so really have only their customer service setup to comment about so far!
I contacted them first by 'phone with a general query about their services and availability at my rural home. Their lines were busy, but a message told me I was at position 1 in the queue (a great facility I've only met once before) and was soon in touch with a rep. A week later I decided to transfer to them, so 'phoned again - spoke to the same rep, who remembered me (!) and made the necessary arrangements. Within ten minutes I received an email listing (correctly) my requirements which was followed five days later (including a weekend) by a router and confirmation letter giving also my activation of service date. This date was met and I went live without even noticing any "downtime". Indeed, it was only when I noticed that my internet download speed had increased five-fold that I realised the transfer had been effected!
I've contacted the Phone-Co-op a couple of times since, to confirm a point or two, by both email and 'phone, and had a rapid and satisfactory response each time.
I agree with Mark.J's comments re the listings. I assume they are a small ISP but I chose them because they are the highest-rated company in the Top50 which met my requirements at, I must say, a very competitive price. Assuming that their product is as good as their customer service, then I shall have absolutely no complaints.
