Oh Dear, after reading this, I followed the link and gave them a totally negative survey!
Everything I buy is a one off, I have never used bidding groups and as for phoning me (even if it were available as I don't wear my mobile like my kids do) if I have bid my max, why would I want to increase it?
If their dreams of huge increases in fees come to naught because nobody wants these extra services, will we all be stuffed with extra fees?
