I am happy to say that my problems have been sorted out in a manner wholly satisfactory way , as desired by me. Even after their HR guys promised action on my complaint, these PCI folks have done nothing to help me out. They are big on talk and bad on service. I have thus moved to another efficient service provider.
Stay away from Pest Control of India, Eastern region, especially those who service Lake Town and Bishnupur, Bankura, West Bengal. I had entered into several contracts with them and now my money upwards of rs 10K has gone to waste. As per their request here I had sent them the relevant details of my identity they did nothing.
If you have any sense shift to some other pest control provider. They will at least not tell you like their top brass to go to hell.
