the full quote is:

"does not matter if this is an isolated edge case. Data loss for 15 months with poor support isn't something that can be waved off as 'edge case'. The fact I had to go to Reddit to get someone's attention for this is insane. By the way, I tried reaching out to various 'senior management' personnel via LinkedIn last year and no-one replied. Escalation requests via the Support thread ignored and declined. Very professional of you guys."

and that seems pretty damn reasonable of a reply. the fact they had to go to reddit is insane. a sarcastic "very professional of you guys" is pretty tame, given the situation, and not discrediting at all.
