Frustrating working with *********** staff

I have a Dikhololo timeshare and was very happy with how it worked when they were on their own. Since they have joined Iexchange the personal touch is gone and the staff at Iexchange is totally ***********. I have tried to sort my banking of points out for more than 3 years now. I live and work overseas, so it is hard to phone due to time zones. There is no way to work via email, and the once when I spent $50 on a call I thought the issue was resolved, just to find out today that nothing was fixed. I wish I could get hold of an email to contact the owners as I am not sure if they know how *********** their staff are.
