Symphony — storm 100i (poor service)

I had registered a complaint regarding my cooler (Storm100i) on 8th june and till now nobody had even visited and resolved the problem. You promise to pay a visit in 24to48 hours but now its almost 9days since i registered the complaint. I am a retailer of your coolers, so do have contacts with your dealers and even though the complaint is not getting resolved any sooner. Either you resolve this problem soon else i would have to take strict actions against your company/service providers.
