Was I scammed by CoinSource?

I've run a great deal of cash through CoinSource ATMs in the past couple of years. Always went through within a couple of hours.

Last week i stopped to put in a small amount. Got a receipt that purchase was successful. But its now been a week and the transaction has still not been confirmed.

Texted help after 24 hours who assured me that it was still processing but they were having network congestion due to high volume and it would go through.

Texted again at 48 hors and received same response.

Texted a 3rd tumwvat 6 days and they didn't bother responding at all

What is the longest time it has taken a transaction to be confirmed or have i just been robbed?
