DO NOT BUY FROM ADVENTURE BABY!
I had to write to try to prevent anyone else having to deal with such unreliable, unhelpful people - I bought a pair of Hunter wellies for my god daughter which were the wrong size and they didn't want to know. I was on holiday at the time so my friend contacted them and they said there was nothing they could do, as soon as I was back from holiday (and outside of the ridiculously short 7 day return policy) they also didn't want to know. We only want a bigger size, they haven't been worn and just out of goodwill I thought they might be able to do something. The lady I dealt with was rude, abrupt and clearly wanted nothing to do with it now she has the money.
Please buy through an alternative source!
