In a moment of madness I decided to try Three home broadband. It wasn't good enough for our needs. I returned it within 7 days for a refund. Although I'd been assured the account was closed and there was nothing to pay, I got a bill a few days later. I contacted Three, this was the first hurdle. For a communications company, they really don't like communicating at all. They do everything possible to stop you getting in touch with them. But, eventually, after a lot of perseverance, when any sane person would have given up long before, I found a contact. I was in a chat with someone for whom English clearly wasn't their first language, or possibly even their second or third, so conversation was, to put it mildly, difficult. They did say though they'd closed the account and there was nothing due. They sent an automated email confirming this. Then I got another bill. I contacted Three again and was assured again that they'd closed the account and the balance was zero. They sent the same automated email to confirm this. A month later, I got another bill. I got through on chat and was told my account was closed so to verify my identity they'd email a code. The code clearly said "Three staff will never ask for this code and you must not share it" the advisor got quite uppity when I refused to share it for this reason, but did eventually settle for taking my name and address instead. They were less than helpful though. Indeed, I'd say downright rude. However low my opinion was of Three, after dealing with their complaints department it plummeted to a new low. I asked for a handwritten email from them confirming that I could ignore the bill and face no consequences. They refused. I asked to speak to a manager, they refused. They said neither they nor their manager could write emails and that this was company policy. A communications company that doesn't let staff send emails! After 40 minutes the advisor did let me escalate to a manager (or somebody who said they were, but were possibly just sat next to them) I asked them if it was company policy for staff to ask customers to share the code they are told not to share. They dodged the question 3 times, but confirmed it was company policy on the 4th time of asking. Make of that what you will. They also confirmed that Three staff and managers are unable to write emails! So I still have a bill, everyone tells me I don't, and no one will write me an email to say I don't, because the company doesn't allow them to write emails. Although it does, apparently, allow them to ask customers or one-time pass codes. And that is why you should avoid Three.
