poor service

I bought a set of kid's bedding and I received it. when I opened it, it had wrong set of pillow case in it. I contacted homechoice to let them know and I was advised to return them. I have been to the post office three times already and its always full in Rustenburg. I called again to alert them and was told that there is no other way to send it. I then requested that since homechoice is going to send the right set , cant they at least collect the wrong one when they deliver the right one. I was told no and I asked to talk to the superviser to plead with him or her . i was then informed that she is busy she will get back to me till today i am still waiting for her call a week later.today i receive an email telling me that i should have verified that the item are correct on the box before i accept them. is there a way to talk to a client. was it my fault that wrong item was packed . i don't work for homechoice mos. why the person who was packing items for delivery did not verify that the item was correct. it looks to me that all this are done on purpose and make client to suffer .now i am stuck with the item that i did not order and now its my fault. i paid for delivery. its only fair that you guys collect your item back.now i am paying for the goods that i am not happy with.

this is the email i received
