My work phone is on Vodafone, their network is still as shite as it’s ever been.
I’ve worked on a couple of projects at their head office in Newbury. Totally fucking chaotic in there. Big purpose built offices but never anywhere to park, they bus their staff in from park & rides outside the town. When you finally get in there, there’s not even anywhere to sit - everyone’s crammed in two per desk. Even in the canteen there’s half a dozen Indian IT workers with their laptops on every flat surface.
How they were the biggest & most profitable UK company for so long I do not understand. The phone business must be an easy one to succeed in, is all I can think of. The staff in the shops want to help you, but their back office lets them down very badly.
