Thanks for your reply
I just have two questions now.
1, EE can sort out the NM if I speak to the Fault Management Team?
2, What was the likely cause of the high NM's and massive loss if signal?
Sorry to keep asking questions, but I'm sure EE could do a little bit more for the customer than arrange a OR Engineer visit in 6 days after reporting the problem.
Thanks again for all your help. It's greatly appreciated and very interesting
