O2 is a dreadful company, and their customer service (to UK customers, I should specify) is abysmal. My long career as an O2 customer/victim (since 2014) has had its ups and downs, and there have been experiences good and bad. But mostly bad, and my most recent exchange has led me to post this review, so that others might be forewarned. Long story short - a month ago, prompted by O2's merciless campaign of ads to my mailbox, I took them up on their offer of a Galaxy watch on a modest data/device plan. Key point to note is that I added this AS A BOLT-ON to my existing plan with O2 (which had long given me free calls and texts, plus 5gb of data a month). The folks who put the transaction through messed up the deal. They put the watch through as an upgrade rather than a bolt-on, which immediately downgraded my existing plan, and left me in a position whereby I now had no calls or messages, and only a fifth of the data, covering both devices (phone and new-fangled watch). Hence endless costs incurred to my account, and texts on a weekly basis telling me I was 80% through my data. Guess what happens when you call an O2 call-centre? It's a bit like the bridge scene in Apocalypse Now. You know someone *must* be in charge, but god knows who. Distant music plays, interrupted by static. A voice murmurs in the distance. Chaos reigns. The centre cannot hold. Am I still here? The horror, the horror. After two hours, I'm told by one of the automatons, via live-chat, that it is now too late to return to my old halcyon airtime/data plan, because too much time has passed since I ordered the watch. Dealing with O2 tonight brings to mind Gen. Kelly's description of working for President Tr*mp: "We're in crazytown. I don't know what any of us are doing here." I hate this company, hate them into little pieces. They practice state-sponsored larceny, grinding every penny they can out of working people in tough times. They take us all for fools. As patchy as the EE signal is around here, I would far rather give my money to Kevin Bacon's retirement fund than prop up this wretched, hateful company one more day. So loooooong, jerks! (ps. I will say that Carla, who ultimately helped get me out of my abusive relationship with this company, was very empathetic and courteous).
