Terrible customer service, nobody answers phone except for revenue issues. Owners and realtors have issues with inaccurate property information. They do not correct erroneous listings in reasonable time frame. The zestimate is misleading and only licensed property appraisers should be able to make this determination whereas their logarithmic formulas are not accurate and in many cases harm property owners and purchasers. They are political and use this to injure people who do not share their views. Feds need to break them up now.
