I can not believe the customer service we received from Three. We moved and though our Wifi router said full network we were lucky to get a text only webpage to load on our phones. We had a look and there was work being carried out on a nearby mast. Okay fair enough, so we waited about a month and then private messaged the three uk CS twitter. They said it would be done within the week. One month later still no signal so we used the live chat and it was like speaking to a computer. They did not listen at all and told us we needed a new sim card even though it stated on their website they were carrying out work! We then called the CS line and the first agent didn't respond we could hear him playing what sounded like a play station in the background! He then hung up on us. We phoned up again and this agent was so rude to us. I work in customer service and couldn't ever imagine speaking to someone the way they did to us. Let me give you an example. We have x2 wifi packages with three (work and home) and also x1 mobile package so £100+ going to them every month. We wanted to find out when the mast issue would be resolved and the agent was asking for details on all three different accounts (you need to set up each one under a different e-mail etc). We asked for a little minute to double check our info on our side to confirm which wifi box it was and they replied 'I am finding all of your wrong answers exhausting'. We spent four hours on hold, live chat and on the phone that day. What a waste of time, and an instant loss of customers. After research I don't believe theres issues with the mast, I think they are oversubscribed and don't have the capacity to provide to this many customers. Please beware. My partner is now in the process of switching to o2 who I've been with for years and cannot fault and our wifi has been switched to NOW tv broadband who have also been great so far.
