all slimming centre is almost the same..I'm also the victim. Sure cannot refund..they will ask u to convert to others treatment but...need to pay extra money somemore..Sigh..No reason for them is acceptable for refund. Girls, please don't buy the supplements or slimming pills, coffee, or any oral intake products from slimming centre..Dangerous! One of the well known Slimming centre who sell slimming coffee can reduce 3-5kg within a week. I personally tried the coffee, side effects are heat beat increase, nausea, dizziness, loss of appetite and feel uncomfortable for whole day, so i stopped it. I feedback to the consultant, common answer from them" this is a normal reaction because increase metabolism rate and burning fat". I suspect the coffee contains of Sibutramine (appetite suppresant drug) which can cause people loss of appetite. Anybody tried slimming products with this kind of experience before?
