The Big Makro Con

So early December I decided to go to Makro and get my liquor bought before the rush, got to the teller, found out by looking up on the monitor while I waited to pay that I get a free 6 pack, cool bonus, also weird no one told me this, so I go try look for this free 6 pack, manager tells me that they have no more stock left, so im like ok so let me just get a cheaper version and call it quits, but Firstly I had to go into the back and check if there was any stock, weird as I dont work there, there wasn't any, I asked the manager so wjat can we do here, she just said, cant help u, ummmm ok, so we left, but when we got home we found out that something we bought also had a free gift again why no one tell us this? So I emailed Marko, I got the generic response, a week later a lady from makro calls me, asks me to hold the line as she getting the manager, she never answered so I kept being put back to this lady, the phone hung up and I called her back, I eventually gave up as no one knew who I was talking to, oh I got sent through to the manager again, but no surprise she never answered, again, weird as why call me and say the manager wants to talk to me then never take the call. So I email again, another generic response, a week later again I email, and again dame response its been over a month now, I would just love if we could put this to rest, just say, hey, we dont give 2 f@$ks about u and u know what i would just agree and move on.
