@ waltergmw - why would the MAC be required a 2nd time after its been used? sorry for sounding a bit confused..its not hard to confuse me hehe , all I know is you have 30 days to use a MAC, you could use it on day 29 but yet have to wait up to 4 weeks for your installation, this means 2 months after you got the MAC you get it installed
I read today that Openreach are making 2013 installation dates now (since end of November) because they are so busy!
