False advertising/bad customer Care service

Went to Burger king The crossing/Mahikeng with my kids for first time, since it's new in the area. It was packed but we waited nonetheless. Ordered 3 triple burger Meals and 3 kiddie's meals on special that time. Never seen burgers like that in my life, patties weren't looking good, burgers were very dry with no cheese or sauce. We couldn't eat those burgers. I immediately took pictures and emailed burger king south Africa, since I couldn't go back to the shop, they responded after 4 days or so...after threatening to report them. I was given the case number while the matter is being investigated. After a day or 2 I was told case has been closed, no way forward or solution on the matter whatsoever. I've been on their case, sending them emails everyday, trying to find out if I can be refunded...or something. They've been ignoring my emails and still are to this day.
