VERY VERY BAD SERVICE

I bought a thule bag from their website worth R3000, after a few days of non resposnse from them, not responding to my emails and calls, i finally got hold of them becouse i wrote a review on google about this, i asked them about my oder, turns out the backpack is not in stock, they lie and say their online service suport was offline and they will get back to me within an hour, they never did. fine! now its been a week iam struggling to get my refund from them, they say i must follow up with payflex, as if its my dutie, as if its my fault they advertised bags they did not have stock of, very very dissapointed in their service, will not recmend them to anyone.
