Sonic Drive-In at 118 Steven B Tanger Boulevard, Commerce, Georgia.

We have be going to this sonic since it opened and the last 6 months haven't been good at all. After 5 pm we have to wait forever to order and get our food and its wrong even the ice cream cones we got the other day had chucks like it was not mixed all the way. Today we was told they couldn't serve us until they got drive thru caught up after we waited almost 10 mins for a answer. I have talked to the manager but nothing is being done.
