Thanks to all for the interest and advice.
I know Weaver is a big fan of A & A, I have no doubt their support is very likely the best currently available however, just out of my price range.
I've been with Plusnet for over 11 years ADSL/VDSL, never had any issues until the new billing system was introduced, nothing but issues since then which they seem totally incapable of fixing at source, just go around in circles month after month, must have cost them very heavily in lost customers.
Never really needed tech support until April this year when I feel I was was badly let down, yes, was in the middle of the major covid lock down but I felt they used the situation to opt out of responsibility and could have done much more to help.
All support has become even poorer now, can't raise a support ticket on line any more, chat line is closed, only leaves the very frustrating and time consuming telephone support (not 24 hour).
In response to my unresolved closed out ticket issue reported in the first post, I managed to raise an on line complaint ticket which did produce a telephone call the next day from a very polite lady who I felt genuinly tried to help but sounded more frustrated with the situation than myself and in the end was not in a position to provide any answers or solutions!
So, I like Zen, but to be honest if I had the option of a faster cable or fibre connection at comparable prices then I would probably go for that in preference to any FTTC connection, what speed would your Virgin cable connection be at?
By post code indicates up to M350 service with Virgin Media with current offers available.
Yes, I know it would make sense to consider that option but I just have a bad feeling about Virgin Media which I can't really substantiate!
Perhaps my perception of cable will change after a short contract with another ISP, inevitable further degradation of OR FTTC service with cross talk and the frustration of FTTP non-availability in my area?
I like the 12 month contract availability with Zen, fewer ISP's now provide this with 18/24 months becoming the norm, if things don't work out it's cumforting to know that the choice of trying another ISP is never that far away without the hassle of trying to negotiate around contract early exit charges.
