This sounds so familiar, the estate agents get your money as does the builder then when you have problems they do not return your calls or e-mails and you only get certain things solved when you are out there.
talk about patience and diplomacy when you feel like screaming at them.
As a widow and out there, no Turkish work man is safe, once on the complex he does not leave until he has helped me, get my telly working, as my Turkish phone, my washer, hot water and cleanliness of the pool.
So far they have been great.
