I'd not appreciated how bad it was until I'd been there, 15 Jan. 2015
My retired parents had mentioned that they had an issue with cold calls throughout the day. I'd not appreciated how bad it was until I'd been there. A good customer of mine had a similar problem and when I called him for the first time after he'd installed the new phone I went through the filter system. it's fantastic and so effective but simple to use. I'd bought it for a Christmas present and its made a huge difference to their well being and for such a small price.
