Mpell Solutions does not asnser phone calls, does not respond to emails Internet, California

I received this email from Wynham Rewards.

When I tried to complete the form online with the certificte codes the mpell solutions system would not accept the codes.

I then called the 800-450-1575 number the representative  said she was able to put the codes in and I would receive my gift cards.

Now we are at the end of December and still no gift cards.

When I check the status of the certificates  the response is "not valid." When I call mpell solutions I'm on hold for over an hour and then when I push 2 to leave a message no one calls me back.

When I call wynham rewards to tell them what has happened they tell me I have to deal with mpell solutions.

I'm entitled to 3-  $20 gift cards.

Here is my original email from Wynham Rewards.
