You're being very patient and putting your feelings very politely. I'll try to do the same. I've had an email problem since early yesterday. I can't get anyone to answer the phone at PlusNet. I've tried 6 times, on most occasions hanging on for over 20 minutes. I've raised a support ticket and it's now over 34 hours and I haven't had a reply.
The lack of customer support when there is a problem (in this case, caused by PlusNet) is making me look elsewhere for Internet service. This is a pity because I've been with PlusNet for many years and, like you, have referred others to it.
