Eureka Forbes — Quick clean DX vacuum cleaner

I have been trying to get dust bags for my vaccum cleaner for the last 2 months and the company says they will send a technician to my place and charge me 550 INR just to deliver a 200 INR dust bag. I said that I can pick it up from the nearest store / service centre. I visited the service center address provided by the online customer service agent, and they didn't have the dust bag and they told me to contact the customer service again. Its been 2 months the machine is lying useless in my house and I am trying to get the dust bags going round and round with the customer service. Please help
