OK here's the really bad guide to how cell incidents work. This is for all networks, they all have the same drama to follow because they pretty much all share sites. 4G on Voda is shared with O2 for sites, EE have a bulk deal with three through a 3rd party company they formed together and outsourced the support to.
1) Site incident happens, alarms go off in the control centre, incident opened.
2) Try to fix incident by remote, try to turn it off and on again in your best roy impression
3) When that fails, try to contact Landlord and get permission (Written

) to go on site to fix it.
4) BIG OL PROBLEM BIT - Landlords may suddenly decide to be complete pain, try to ask for money, ask for stuff not in their agreement, not allow access, "lose" the keys, you name it, they can just be a huge time waste in the process. The ones that take months to fix are these, there is no reason a network wants it's mast down, they are assets that need to be used. I assure you, mast down is a lose lose for everyone.
5) Get on site, diagnose issue.
6) Are replacement parts needed? Usually a same day thing (otherwise it's back to written permission for another day!) otherwise try to fix etc...
7) quick few tests
8) join site back to network
You can check which mast you're on with a few apps (You're after the cell ID number) if you want to track yourself. You'll probably go through quite a few masts over a 4 mile journey.
Richy, I assume you're going to offers.vodafone.co.uk? I set up both netflix and spotify in the last month through it, I already had accounts with both services and just tagged them up OK. Support can manually add them if you can't get it working but I realise that's not great news.
If you're doing netflix make sure you do the free trial first and then sign up, I think netflix is only 6 months rather than a full year like spotify (make sure you check) so you want to squeeze in that free month and get 7 free if you havn't already done it too
