I was coming to the end of year 5 last September, Aperture had a third party firm contact me regarding releasing equity from my home to pay a Final Settlement figure, This was arranged and paid to Aperture at the beginning of September, since they took the money I have heard nothing from them what so ever, I have sent numerous emails and tried calling them, The automated service puts you in a waiting que for 30 mins then hangs up (every time)... I did get some mail from them this week 3rd of feb dated 15th November which was an annual report WHICH DID NOT include or mention the final settlement paid in September. This should have been closed by now and certificate issued........ just can t get in touch with them... what now ?
