for me, without a name attached to it, the complaint means nothing. I had an issue with a provider (non-deposit related) and when I posted here about it, the provider was suddenly very quick to want to resolve it. I would imagine you will have similar reaction, so I encourage you to do so.
side note - I have followed this simple common sense rules - SMALL deposit ($50 max and/or uber covered) to well reviewed provider both here and rentmen, and never to a provider who lists or indulges in PNP. Any and all horror stories I hear on these forums people have deviated from these common sense rules.
