Ackermans keep leaving security tags on their items

I bought a Jersey at Aclermans Zewenwacht Mall. When I wanted to wear it this morning I saw the security tag still attached. This is not the first or second time it happened. I now have to spend unnecessary money to go back to the store to have the tag removed. I also no longer have the receipt of the purchase, so they might think I stole the jersey from the store. I am beyond disgruntled!!!!!!!!!
