Cin7 Core

Recently after the merger with Cin7 (previously dear system), the support and issues have increased. We have a major bug in product integration for last 5 weeks and still waiting for resolution. For them it is not a priority and no proper work around provided. Not sure if this is faced by any other customers.
No escalation channel, no account manager support.
We are a customer for last 3 years but now looking for replacement.
