I bought two above products but when i opened products at home. Cleansing milk was 1/4 in bottle and anti aging serum bottle was all empty. When i visited at vlcc to complaint about this. The behaviour of staff was very unprofessional and way of talking was very cheap. To see their behaviour i requested them to refund my money back and gave their products back. They kept my products and dint give my refund. They noted down my number and said they will revert me within week. After few days i made a phone call to them but they spoke very harsh to me that "one week to hua nhi abi. Wait kro"after saying that she cut the call.2day 1 week is past but i dint get any call. Please help me to refund my money and initiate compensation for their bad behaviour and harrassment so that they never try to harras next person.
