I've purchases a 3 Tier License and I set the service aside for about a year without using it. Then, one year later I found that the app displayed an error to me related to unpaid invoice.

When I tried to get help the OneUptime company was extremely slow on responses, and finally they never reverted my access to what I had purchase on AppSumo.

First they provided me with a new discount coupon on a product that wasn't equal to what I purchased on AppSumo and then me, by mistake I deleted my workspace. Then to create a new one I had to follow again the purchase process by using a discount coupon. To proceed with this I've asked for a new code and they provide me with one that never worked. From that point I've send multiple requests for a new code and they never send new code!!!

It's a shame ! Because of their internal problems (the displayed the error with the unpaid invoice) I wasn't able to access the purchased service and then they refused to support properly !!!
