Presto works decent, but there are some major archaic practices here that need to be updated to 2018.
1. The initial card purchase and the delays to get it working, this thing should be instantly activated on purchase not 24-48 hours later.
2. Machines constantly out of order at most stations.
3. Machines that promote monthly passes but don't have the functionality to do so.
4. Tapping on to subway only to find out there is a massive delay or stoppage, there is no way for you to get refunded unless you login online and make a dispute. There should be a tap off option managed by the transit staff or easy way to do this in an app.
5. Refunds take days to get loaded back to the card vs instantly.
6. If you want to close your card and get a refund you can at a random store for cash. However if its over $50.00 you have to Print a refund form, ill repeat that. You have to print a refund form!!! fill it out and mail it, Presto only processes these once a month and your refund will take 4-6 weeks! This should be digital like everything else in 2018.
TLDR;
Presto works usually, all its services are slower than a fax machine. Good luck getting anything done with there service in a timely fashion. You will need to wait a minimum of 24-48 hours but usually longer especially if it is over a weekend. Upgrade your services to join the rest of us in 2018, stop living in the past.
