I changed my internet provider once, after I was pissed off by their constant stream of calls about their new offers I might miss. It was a good provider for some time, but after his merger with an other calls begun. I told them every time to not call me, because I'm not interested and if I was I'd contact them. They didn't listen. I tried to shout at them, it didn't work either, so I quit. But it was not the end. They kept contacting me for year and half, trying to convince me that they are the best provider here and I should choose them. I was angry beyond sanity, I'm still angry at them.

I just do not dig it, how people stand this.
