Elizebth was not helpful at all.
I sent her email along with my case # as well as I called, she called me back and told me they revised the coupon and they would not honor this. She did not offer any gift card.
I told her that just the last week I bought over $600 worth of goods which she could confirm but still she denied.
Last I said I will return the stuff back to bestbuy and will buy from a different store.
