Ackermans: wants me to bring all the items I bought even when IAM returning 2 with a valid receipt

I went to Ackermans Florida Goldman street, to buy few stuff for my baby's arrival, and I saw few items on sale so I decided to add them to the list, upon arrival at home I realized that very same item that I bought which I thought were on sale I was actually been over charged the mark down price which is hand written is higher than the the original tag price, I called they said in must return them , took my receipt and went there and the manager told me she can't help me since the code of the one item does not corospond to that item despite the name of the item been and there and the same, told her when I bought the stuff the lady who was helping me was not using the Scan but was punching in the code, but still did not make sense to because the name is the the same, she told me to go back home bring all the items that I bought so that she can check them and see if that item is on the receipt despite me having the receipt with me. The level of service I received is totally unacceptable and considering that I am 38 week's pregnant been taken to Piller and post. And she refused to help me , I would I bring stuff that I don't want return back with me, IAM not even show if the manager understand what customer service is, she does not have common sense.??? Everything is on the receipt yet u want me to bring all that I bought , does she know that I use my petrol to go to the store and come back home, which they will not compensatee? And yet if it was a white person she was gonna help very quickly and even get an apology, this people think we as black people don't have the means to complain and will just accept any treatment that's thrown at us.. ??? that was *** service I received..
