Go back to the store on a Saturday afternoon,
or anytime they are busy, do NOT cuss or get angry,
but do talk a little louder than normal. Tell the
salesman you made a purchase last week and are un-happy
about the sale. Ask to speak with the owner / manager.

By calling them on the phone, you made it much to easy
for them to say no.

Good Luck
