McDonald’s complaint: Incomplete order at drive thru

I had placed an order for two double quarter pounders with cheese. Got home and they were only single quarter pounder with cheese. I called spoke with an employee. Gave my name went back the next day to try to make my order correct. The employee never took down my name or my complaint. Went back through the drive through the next day. That employee was not helpful at all.
Not that I had to go through the drive through it was convenient for me being that I have an amputated leg. So I went in. The Manager said do you have your receipt I said no. I explained I called the night before. The employee was apologetic. The manager said snd very rude. Your name isn’t in the book no receipt I can’t help you. I will lose my job. I said I am going to go out of my way to come in hard enough to get around with only one leg and have a manager be rude to me. This is just unacceptable.
I guess your managers need training..
