Heres my BT experiences..
Ordered a phone line online. First mistake. Never order anything online with BT. 3 working days passed, no contact about an install date. I rang BT, spoke to a lady who informed me "online ordering sometimes doesn't work, even if you get a confirmation number". Her exact words.
So I gave my details to someone else, some fool at BT who would then give me install dates. Only, he would say something like "Friday 24th September" and I'd reply "Err.. the 24th is a Monday".. and he would go "Oh sorry.. yes.. how about Wednesday 25th Stepmber" and I'd go "Err.. the 25th is a Tuesday. It was THAT bad. Clueless. Every question.. the reply.. "Oh, one moment, I'll need to check with my manager on that" in a really squeeky voice. I asked "Do I need to give you any bank details". "No sir, that will be covered with your first bill".
I arranged an install date. Then I got a garbled voice mail from someone at BT asking me to ring back. So I did. I was then told my order had been stopped because I hadn't given any bank details. Joy. They then informed me I had three orders in the system. I quickly told him I just want one line!!!
So I was given a proper install date. And to be fair, the BT install engineers are great. Arrived bang on 9am, polite, asked me about my move, really nice chap. All done in 5 minutes.
Then a week later I get another phone call from an engineer who is "1 hour away, shouldn't be too long now, get that line installed for you". I quickly ring him back. "Must be a mistake mate, I've already got a line!". I then spent 30 mins chatting to him about my BT woes, and asked him what he felt the chances were that I had two active accounts in BTs system. We both agreed, fairly likely.
And indeed, I am now getting 2 bills for 2 lines. Only one is real, the other was a ghost on their system.
So a month ago I rang up, spoke to a guy, who told me he would deactivate the ghost account. Every week since I've gotten reminders.. some blue.. some red. I worry when I get red reminders. I don't want some black mark against my name. So I rang up again, spoke to someone else. "Oh yes sir, thats marked to be removed, no worries.. just ignore the letters". And again.. I rang up, same reply.
So when I ring up tomorrow I'm going to go mad at them.
In all I would guess I've spent what.. 8 hours waiting in queues.. been disconnected once after 45 minutes.. spoken to several people who "Can't help with GB accounts".. great stuff.
BT.. utter s*ite
