I wasn't involved, but how nice for someone to make the effort to make amends for a problem they perceived they had caused! Well done mate.
Just a point of information: Don't be fooled into thinking that the centre controlling you is co-located with its transmitter ("i assume i was just too far away from west drayton and too low to receive you."). We have transmitters and receivers for various frequencies located all over the country at places which should give coverage throughout the airspace to which those frequencies are allocated. If we did not, I think that when I am sat at my console near Southampton controlling an aircraft in the middle of the North Sea or 100nm west of Lands End I might have trouble making myself heard!
