I brought in the blade on a Saturday thinking they would do it that day. I was surprised when they said it could take several days but that it would likely be ready on Monday.
After more than a week I had heard nothing so I called and was told it was still not done. I told them I would be by later that day to pick it up even if it wasn't't done. I showed up a few hours later and found the job was done.
I emailed twice to ask about the poor customer service and never received a reply.
