Unable to cancel my order

I placed an order on Saturday night, immediately after placing an order I found that I placed a wrong order and I tried to cancel. I tried locating the cancel button, it was nowhere then I tried clicking on the chat window on the right-hand side bottom, it had only 1 option to "Get help from the community", somehow I managed to find the email of support help@ring.com.I have written the mail to them withing 10 min of placing the order, got an automated response immediately. I tried calling them and selected option 4 for Order Status, the call got disconnected I tried multiple times. I waited till Monday, still no response to my mail, then I sent another mail on Tuesday still no response. And Now my order is delivered.They have an option to return but that would cost me $5 which I have to pay from my pocket without any of my mistakes.This is so frustrating. I will never buy anything online from Ring.com again. This also raises a question on the support which ring is providing for my alarm system.I understand that their systems are overwhelmed by the pandemic this is not the excuse to mishandle the orders, if ring.com just provides a small button somewhere in the page to cancel the order, this will save so much time, frustration for us and for the ring. This is so bad.
