Theodore & Pringle Optical in Real Canadian Superstore

Both my husband and I ordered 2 pairs of glasses. The optician was friendly and all seemed fine. When we went to pick up our glasses, my husband said the lens were giving him double vision. No problem, we will fix it. He had another eye test and theyfixed one pair. No different. The optician then informed my husband he had one more chance to get it right as if it was his fault. I asked her or what? And she informed me I would get a PARTIAL refund. WHAT???????
