In Hungary in general, in my humble experience, the services sector has a long way to go to understand the concept of customer service. Not just letting agents, but banks, the state sector and tax offices, lawyers and accountants all need a good kick up the This post will be deleted if not edited to remove bad language to wake them up and get them to understand the needs of customers. There are exceptions, but the above is generally the case.
My approach to this kind of situation is to try to work with what you have instead of wishing it was different. I get to know my management company -- particularly the person dealing with my business, and I make an effort to keep in good communcation with her. I take her out to dinner when I am in town, and I give her a small gift at christmas and on her birthday. I give clear instructions as to what I want, so that there is no room for confusion, and I respond immediately to any emails etc.
Hungary for me is a holding situation, waiting for the economic improvements that I believe are there in the medium to long term, and I just want a hassle free working arrangement in the interim. I don't expect instant results, but I can already see an improvement in the service level in some banks for instance, instead of the "take it or leave it" approach that was evident up to now. I expect that management companies will also get their acts together as the service ethos gradually takes root in Hungary.
