Painful journey to receive a refund

I bought an item using a credit card on the 25th of January then decided to return it on the 28th, I was told refund should appear within 24hrs in credit card account. Until today there is nothing, I want back on the 2nd of February and I spoke to one of the managers who sent all my paperwork to rcs refund department unfortunately not feedback even now, its been a week already. I will never buy anything from them even if they say 90% sale I WILL Never!!!!!!!!! I just need my refund that's it. Should you see in any Edgars store Pls call the police. Poor service which is accompanied by useless systems that fails to process a simple thing "Refund" Mxm
