Pink Threads Boutique - Wrong product replica sent

I ordered a dress from them and paid **** and after * days they called me stating that the dress is not available and asked to pick another dress from the available of mostly *-** dresses and they claimed that the dresses are worth *k and giving for less price as it is their fault and forced me again and again to pick and I picked a dress when it was delivered it is of such poor quality and a replica product, so I returned it and asked to refund now they are denying it and asking me to pick a dress from the available very few dresses. So shamefully cheating customers with replicas and such high cost
