Talk Talk...
Not the band, but the dreadful telecommunications company.
We were without phone and internet while with them for 6 weeks. I phoned them virtually daily, having hiked to the top of our hill where there was mobile signal and heard nowt but excuses for why it wasn't fixed. Then they cancelled the fault ticket, twice, so I had to start all over again. And the fault turned out to be exactly what I'd told them it was - whoever had laid the cable had done it very shallowly over the corner of a field, and that had been ploughed. The same as it had the year before when our phone line had gone down the first time.
But their general incompetence was unbelievable - we're talking worse than British Gas!
Though SSE, who I'm trying to deal with at the moment are approaching those levels of rubbishness too!
