I had a huge amount of buggeration with an ISP called Jazztel after we moved to our new flat almost two years ago. This was because they had been supplying internet ADSL to our previous flat in Chueca, and refused to accept that we would no longer be needing their service once we'd moved. I actually paid them for about three months' worth of service that I never used, and had one hell of a time getting them to stop pretending I was still their client. In the circumstances, I think I was more than generous. And they were just stupid, arrogant SOBs, to the extent that, once we moved to our new place, we would get at least one phone call a day from their sales folks imploring us to switch to them. I don't have the Spanish to say 'I would only sign up with Jazztel again if I was the last person left alive on Earth', and so I would just say 'no thank you' and slam the phone down as hard as I could. I know, I know, most telecoms companies are like this - they all probably make significant amounts of money from ex-customers because those wanting-to-be-ex-customers didn't resign properly (I believe the only acceptable way of terminating a contract with Jazztel is to write 'I quit' on the left-hand side of a Tibetan mule between 1158 and 0002 on the 30th February and posting said mule to Jazztel HQ (somewhere on Planet Jazztel), supplying enough postage so that it arrives no later than midnight on the 30th February the previous year).
Total stupidity prevails again
