McDonald's

This was the 3rd time in a row that this place has gotten something wrong on our order, so this time my wife checked it before leaving.
After pointing out a missing order of fries, she brought the food home and halfway through my DQP I realized it was only partially cooked.
This is so far beyond "replacing the item" at this point.

I ordered two mcflurries for pick up through the drive thru.
One oreo mcflurry with extra toppings and one m+m mcflurry regular.
The screen read one oreo mcflurry that was charged, with charges for each of the extra toppings and one m+m mcflurry charged.
Those were the only two items on the receipt.
I apologize dearly beforehand if the women in the second window happens to be undeveloped, but she was very unkind and rude.
I somehow got two oreo mcflurries with no toppings in either.
When I had gone back to get just the m+m mcflurry, the women in the second window was not cooperative even after being shown the receipt.
She tried to send us off saying her screen read two oreo mcflurries and told us the toppings were all at the bottom in one of them.
I again repeated that there was an m+m flurry on my receipt and again showed her my receipt.
After the women finally gave up the arguing, she went and got the m+m mcflurry and handed it over very obviously trying to be rude.
The m+m mcflurry appeared very melted compared to the others she just had handed me and neither of the oreo mcflurries had the toppings like she said there was in one.
My opinion? I don’t believe the melted ice cream was a coincidence but purposely done out of spite from the worker, nor the missing toppings, nor the quickly whipping up two oreo mcflurries to quickly get the order done.
I have loved mcdonald’s my whole life, always have, always will.
Everyone’s aloud the tough days , we all have them but to be this unpleasantly rude over your own mistakes is actually mind blowing.
The women made me very uncomfortable and made me feel unwelcomed.
There’s millions of other locations I can surely go to and have no problem with doing so but please Mcdonalds, you’re a huge part of peoples everyday lifes, make yourselves aware of the situations that occur in your very windows and hire people in the window who can handle small stressful situations such as this one properly so customers can go back to having a pleasant expierence at mcdonald’s, instead of dreading of going because how rude the workers can actually be.

For what they charge, this is a FREAKING JOKE.
I paid extra for a large fry, and this is what was in the bag.
No fries spilled in the bag either.
This was it.
