I’ve had to ring EE three times yesterday (my phone arrived on Friday), because I found that while coverage, including data coverage, is pretty decent in the area, there was no signal in the house.
First call – they suggested a couple of things on the handset to try, no to call them back if that didn’t solve it (it didn’t).
Second call – ok, we need to check if there are any issues in your postcode area…..sorry, that system is down, can you call us back in a couple of hours when it should be up and running again.
Third call – there are no faults or issues in your area, it’s basically your house that’s blocking the signal. Ok, what do we do about this? I’m sending you a signal booster which to plug into your wifi router. How much is that? Free.
So I’d have to say the three customer service people I spoke to yesterday were all pretty decent and seemed keen to resolve the problem. I know those signal boosters are supposed to cost £100+ , so if that solves it and costs me nothing I don’t see anything to grumble about.
