I advised the consultant to call me back as I wanted to give him my children particulars. The consultant never called back and I just find out that they have been deducting all these years and I only canceled this year.<br> <br> I sent an email to their complaints email and they never returned to me, I also called and I spoke to the consultant who advise to get back to me and till today I had never receive and feedback.<br> <br> I do want a clarification on how did they deduct my money without my authority.
