Club Factory — delayed order delivery and not getting that order

I ordered from club factory on 21 april with order no. So[protected], there were 7 items in the cart, some of them were out of stock and some areetioned to come by 9th of may but still not get those items, called and n helpline number but no response as nobody received call and after that no procedure to contact with them.
I want to return those items as my need hasn't fulfilled by time and now i don't want them and i want to have my refund as soon as possible.
