Poor service and customer service

I logged a complaint more than 2 weeks ago and only yesterday I received a notification that they are looking at the complaints. Case nr 408624. Yesterday the manager called me and wanted to know what the complaints were about, I had to explain everything again to her and she said she will check with the employee and come back to me the same afternoon, no surprise I have not received any feedback as yet. This is a well known eatery that spends millions on advertising their products and then one experience such poor service!! Not once but twice within a week??? Unacceptable!!
