Alexander, good afternoon,
Don't take it as rudeness, but I'll answer right away in essence:
1. OneBox technical support through this forum is public and free, and response rates are not regulated. There is simply no other support for OneBox.
If you need technical support on other terms - please order it from integrator partners
https://crm-onebox.com/ru/integrators/ for money.
2. Regarding the contract, since you raised this topic:
> And also, if we talk about the timing, then it is written in my contract that OneBox undertakes to solve the problem of system bugs within 4 working hours after the appeal.
Yes, but for OneBox CRM+ERP (version history here
https://crm-onebox.com/version/)Yes, this is such a life hack that we are forced to apply.
If you think this is rude and dishonest, then is it fair to maintain and update the system for free forever to customers who paid for it once? (it was a rhetorical question).
