Wow!
The power of the Casinomeister knows no bounds. Within 20 minutes of me making the above post and sending an email and PM to GrandVirtualCS, I have received a response. As I said when thanking him for the response "it is so nice not to be ignored". I've been sending them emails for nearly a week and have got nowhere.
Casinomeister certainly unblocks the worst blockages.
I'll let you know whether my problem is resolved.
Do you unblock drains as well?
