i had a load of aggro with bt about 18 months ago when my landline went down(i may have already told you this??) the broadband(sky) was fine and i was gettting 6 volts down my phone line which is enough for broadband but the phone needs 12v
so the bloke came and said it was all fine there was a problem with the exchange, the exchanges are a different part of bt so he couldn't look at it, so they sent a bloke from the exhcange company he said it was fine there was a problem in or near to our house, so back came the phone person yeah it's all fine it must be your exchange
at this point i had wasted 3 days leave already,
so i got my tester out and showed him the 6v it's not the exchange sort it, so he buggered about up the phone pole for about an hour and said it's all fine, what it probably needs is a new line from pole to your house at £189+VAT, to which i replied if that's the case cable will be coming next week and i won't be with bt anymore.
he said but you'll have no phone til then(it had already been 3 weeks with no phone) but i'll just try something before i sign it off, half an hour later the phone line came on and i've no idea why
so good luck mike oh and we got a £5 marks and sparks voucher for all our inconvenience
