I really should learn to read emails properly before posting as this is what it said:

I can confirm that having checked your Sky Account your Broadband connect offer expires on the 15th of July in regards to this i have contacted our relevant department to get this offer placed back on to your Sky Account.
So by the looks of it and if I am reading this right they have extended the 5 offer for me. I guess I will know either way next month when I check my bill online.
