I have been getting calls from them for a very long time (but I never picked up) Finally today I've got fed up with it, so I called back and told them not to call again. The staff was very patient and friendly, and he promised to mark that in their system. I appreciate that... However, I have told them not to call a year ago, it did stopped for a while and recently called again. So let's see if this time they can really do what they promised.
