Massive heads up to the live chat team!!
I received an email this morning say a free product is on its way for me to review (yay!). Then it occurred to me that the last time I recieved this email I never actually recieved the product. So I jumped onto the live chat to check my postal address, which was correct.
It turns out my last free product had obviously slipped through the cracks in the 'out for delivery' stage. A member of the team was more than happy to sort this for me and now (hopefully) I shall be recieveing that product as well as my new one! It's gonna be a busy weekend ;)
