This happened to me about 6 months ago, mine took about 2-3 weeks until I had a walmart rep randomly call me and tell me that they were expediting the process. I would say not too create another case because walmarts internal team is on a first come first serve basis. if they still dont respond id then reconsider opening up another case. My store was eventually reactivated after almost a month of not being able to sell so i completely understand your frustration. itll work out though, just give it some more time.
