I have a Hampton Bay patio set I purchased from Home Depot back in 2008 and I need a replacement chair. Where can I buy one the set is discontinued.

Any number of people may sell it discontinued. My recommendation would be to call Hampton Bay directly and give them the info about your furniture, and ask them what vendors might still carry it.

I have been trying to contact them all I can find online is an email address which I sent them an email on Sunday I still have not heard from them.

Home Depot is a big supplier for Hampton Bay furniture and Lighting products. Give your local Home Depot store a call.
