they gave a replacement sim card to someone pretending to be me without ID and this person hacked my ebay, Apple pay, paypal, and my bank account. it's been over 8 months since this happened and they didn't even apologized, not only that, they also tried to deny responsibility. the amount of stress i had because of this is unbearable, i had to change all my accounts, usernames, passwords, delete accounts, start new ones, running to my bank few times, being with no money in my account for few days. yes i got my money back but this is the least i would expect. i have taken a legal action but guess what, for the last 8 months they keep ignoring the letters my solicitor sent them until only last week when he put more pressure on them they told him that they found the letters. i stayed with them after that simply because they are the cheapest, yes i may be wrong but this is what i did. i was due to an upgrade last month and this was another disaster as i ordered iphone 8 and couple of days after receiving it i decided to change the color, to cut the long story short it took them almost a month trying not to change the color by coming with the most ridiculous excuses in the world, until i told them i was leaving then they changed the color. if saving few pounds a month is not an issue then stay away from them. i remember when they first started in the UK and i tried them and the cancelled the contract straight away due to poor signal and no coverage, it took them 5 months to close the account and give me my money back, so they're bad since they started their business. but to be fair now their network is not that bad however their customer service is the worst in the whole world.
