Wimpy don't care about customers

Just had the worst experience at the Jean Avenue Drive thru. I tried to send the following message to Wimpy afterwards that contain all the detail of my ordeal:

"I ordered some burgers at the drive-thru (Order 73 on 26 July 2022, Receipt R85072, 188141). After 10 minutes I was told to wait in the parking area so that I do not hold up the line (no explanation given why). After another 15 minutes, still nothing.

I left and went to the Steers a few blocks away that served me immediately. Your service is the worst I have ever experience. I hope you enjoy the meal that I paid for, because I will never frequent your shop again and indeed will ensure that everybody I know is informed of your bad service"

Of course, the wimpy complaint line also does not work - the email would not go through after several attempts. Makes perfect sense, why would they care about bad customer service?
