Sir / Madam, We had purchased one ASPEE Duo Fogger Machine from your authorised dealer at Kolkata, GC Avenue. At the time of purchase, four nos of Butane Gas Cylinders were given to us. As on date, all the cylinders have exhausted and we are in need of fresh gas cylinders. We contacted the dealer from whom we had purchased the Fogger Machine. He expressed his inability to provide us the same. Therefore, the machine is lying uselessly. Kindly help us by giving the address from whom we can purchase gas cylinders. Regards.
