Again, don't take it personally, but I've been doing real estate for the last six years and I've spent tons of time talking to other investors and landlords. I also still rent because the returns in SF for buying are so abysmal. So I've had plenty of exposure to the way the real estate industry works. And the customer service is almost uniformly terrible. I read your statement as saying that you didn't want to make it easier for customers to contact you, because they would just whine and complain about stupid stuff. What makes real estate different than any other industry in this regard? What company with good service is determined to not "make it easier for their customers to complain"?
And there are guys out there doing this right. I've lived in building that had online portals for customers to submit complaints and it didn't seem to be a problem for them. And I've talked to landlords across the country who run extremely efficient operations with low marketing costs, low vacancies, and high rents because they kick ass for their customers.
