I get the same thing : mobile phone companies trying to get me to switch to them. No thanks!! im happy with the provider i am with and have been for the last 3 years but they can be darn persistant.
I got right ratty one day with one company who made 3 calls to me about the same thing in two days - i ended up saying p***off to the person on the phone and said id sue them if they ever called me again.
it had really begun to do do my head in. And they wont tell you where they got your num from....gits !!! grrrrrr
I cant stand cold calling - i am quite able to get up and buy what ever i want i dont need some muppet to ring me up and try and sell me something i dont want or need.
