[Resolved]  Lakme — Received a tester on purchase

I am from Bangkok, recently visited India and bought quite a few thousands of Lakme products from KUNCHALS shop at Lifestyle Mall, near Rajouri Garden MRT station. One of the product I purchased was a 'bronze' jewel eyeliner (the bridal sutra collection) and as it came packaged so I open to see the eyeliner tube. When I got back I opened and saw the word 'TESTER' written on the product I bought. I WAS UPSET. I paid and got a tester instead! I wrote a complaint to the Lakme official website and NO REPLY. I complained to Kunchals where I bought Lakme from and after a long time, I only received an apology and an excuse saying it's Lakme's fault! This unbelievable, delayed and an irresponsible reply.
I told Kunchals that I bought the product from their shop and if I got a tester from them, they ought to exchange or send me a new one or do something to compensate. They didn't bother to reply anymore. In cases liek this, it's not only bd service which you apologise and flee. This a case of bad product, they have to take it back, I don't know how many peopel have used the tester and it's eye product also.
I feel like I have been cheated.
Besides teh bad product, the service I got was not even near 'good'
At the Kunchals shop, the sales rep kept pulling my hand from me to apply lipstick to present colours. No manners, they at least should ask if a customer woudl like to try and not just grab my hand and paint someting on my wrist. Worse is at the Westside store in Karol Bagh, the sales rep was a guy and kept pulling my hand to apply products on to show me. He should have had some manners , he can't just pull a girl's hand to try products on.
At Lakme couter of Westside, Karol Bagh - after paying when I went to show my bills and collect the products, they forgot to give me one product, which means I paid for 7 things and they gave me six things. Luckily I checked and told them so the gave me saying they forgot.
Since I bought a few thousands, I was supposed to get a premiere gift, they didn't give me. They forgit again! I realised later and went back to ask for it.
I was already upset with their forgettng and when I return home to find that one of the product turned out to be a tester product, I was furious. AND THE WORSE IS THEY DID NOTHING ABOUT IT! This is pathetic!
Can someone tell me where can I launch an official complaint to the Lakme customer service dept? Pls give an email or someting. Thanks!
