You're lucky to have got an engineer out. When I moved house last year, I wanted to bring my existing phone number with me, which should have been no problem at all. However, I found that my line wasn't working from the day I moved in, and it took about 5 phone calls over a period of 3 days, to convince them it wasn't a problem with my phone, which worked fine at the old address. They were threatening me with a £56 call out charge if the engineer came out and found the problem was my equipment, so I asked them what they were going to pay me in compensation if the fault was theirs, and whether they would cover my mobile phone costs while I couldn't use my landline, not to mention the trauma of not being able to use my PC! Of course, the person in New Dheli I was talking to, then pretended she was not understanding me. I eventually got a grand gesture of £4 towards my mobile phone bill.
