Tigerbrands doom mosquito coil ****er

I bought doom mosquito ****er coils and they do absolutely nothing to mosquitos,I have a video recorderd of this incident and it's a joke,I'd like to know what tigerbrands are going to achieve by selling a product to customers and lie about it. I'm disappointed and dissatisfied with this product and highly recommend that consumers dont purchase this **** product.

Please could someone from tigerbrands contact me via email so I may share my experience and video recording of their product with batch number and expiration date.
