Systems don't work and items were inedible

I am extremely disappointed with the items we purchased at Mugg and Bean Montrose OTM. I have tried to log the complaint multiple times and was met with system failures, I then called the contact center and the guy told me I couldn't log the complaint over the phone and gave me an email address, *** which I did send an email and I did not receive any feedback since. This was over 3 weeks ago. We purchased a triple chocolate brownie which was burnt, hard and dry. We paid a lot and the brownie was inedible and had to be thrown away. The burnt smell was very strong. We also purchased a triple chocolate ****in which was also dry and hard and there was no chocolate in it. Also had to be thrown away. So disappointed as the stuff is expensive and we could not eat the items. And I was given the runaround when I tried to report this.
