The service from PlusNet has really gone downhill. I am moving away from PlusNet now and I am advising all my customers to move also. I have done some research and it would seem the consistently best ISPs are IDNet and Zen.
I have tried to contact PlusNet on several occasions with the intention of introducing new business customers, but I have not yet managed to talk to one human being. When you work your way through the horrendous menu systems and wait for ever only to find you have got to leave messages which never get responded to. PlusNet used to be a good ISP but someone who has mede some serious business decisions has really screwed it up and it must have cost them a fortune.
