Family Dollar

I bought some rugs there and some of the rugs were too small. I have been to the 4 times to try and return. It's either I should come back at 3pm or the manager is not there at 3pm. First why state time you returns and second I got there after 3pm and they have to give me another excuse that the manager is not there. Attached is the receipt, i have the end of this month to return and I will hate to have to waste my time again.Really frustrating.
