Walmart Supercentre Pharmacy

I went to return ...

I went to return a popcorn maker I purchased shortly before christmas. I used it 3 times and it stopped popping the popcorn. I could not find my receipt for it and they refused to do an exchange on the machine. Wasted $70.00 on a machine that was useless. The manager pretty much told me I am a liar and that if I don't show him proof that it was purchased from them that he would not do anything...
