I contacted a prossie via Vivastreet's e-mail system a few months ago, and when she replied asking me to call so she could "get to know me", I replied saying "not at Vivsatreet's secured prices". Whereupon she gave me her own mobile number, at normal rates. After that everything went very well, and I spent a very pleasant hour with her. She's since transferred from Vivastreet to AW, by the way.
