McDonald’s complaint: pricecustomer service

we went to mcdonalds purposely for the 2 for $6 AND the mcrib.sh3e tells us they no longer have mcribs.yet,there were at least 3 different signs advertising it.so,we ask if the 2 for $6 is still on and she tells us yes.so we orderer; 4 mcfish,2 quarter lbers,2 mcchicken,plus drinks.the price rings up over $35 dollars.so we ask why.the cashier says she’ll fix our order to show the discounts.we paid and went to get our order.than i noticed the bill was for over $35.we ask about that and the person giving us our order tells us there is no longer any discount.we askto talk to the manager.she says there is no longer the 2 for $6 sale.we told her we asked about that before ordering.she said there is nothing we can do about that.so we cancelled our order and wanted our money back.we also pointed out to her all the mcrib advertisements and she said nothing she can do.so after a good 20 minutes we got our money back and went to wendys now,let me point out that the main reason we had planned on going to mcdonalds was for the tv advertised specials,of which was still run that day.now i have a very angry 71 yr old plus a couple of kids crying.so i am fed up with this happening at mcdonalds over and over.now i have a 71 yr old that says she will NEVER go to mcdonalds.plus angry kids.suggestions on how to rectify this?DO NOT ADVERTISE ITEMS that are no longer carried or on sale!!! i have had this problem repeatedly at the mcdonalds on 169th street in hammond.now this is the 3rd time i ran into issues at this one on kennedy.if this comtinues i am going to advertise both places on fb and several other sites telling people about these issues,asking me not to go there.adfter waiting in a line at drive through for 15 minutes,we run into this problem.by the time we got home it is too damn late to want to eat.p-lease rectify these kinds of issues.
