[Resolved]  Symphony Air Cooler (Sumo Jr) — Disappointed with the service provided by Symphony

I have bought a Symphony Cooler (SUMO Jr.) from Vasundhara Electronics (Sector-13, Vasundhara, Ghaziabad) on 6th May, 2009. The cooler was deliverd around 11pm hence that day I didn't use it. Next day, i.e. on 7th, after unpacking, when I switch on the Cooler, I was surprised to see that it was not working at all. Only it was making some noise and delivering hot air which can be felt only from a distance less than a foot from the cooler.
As 7th was the Election day in Ghaziabad, I reported the problem next day (8th May) to dealer and on his suggestion I registered a compliant at your service centre (Compliant No. 8/20). This was registered by calling at[protected]Mr. Uday attended the call).
I was lucky enough that your service Engineer (Mr. Jhony Tyagi) visited on 9th May only to inform me that there is fault in the Capacitor and he does not have the spare. Hence we have to wait for the next day to fix the same. The same was communicated by the service centre in the presence of Mr. Tyagi. I have also taken the number of your Zonal Manager, Mr. Vipul ([protected], [protected]) from the service centre to discover that one number does not work and another is switched off.
Next day, on 10th May, I discovered that it is Sunday and your service centre remain closed with the numbers I had was in switched off mode.
On 11th May, Mr. Tyagi visited our place and discovered that there is no problem with Capacitor and this time he told that Motor is not working and it generally takes 7~8 days to replace motor as service centre do not have stock. When discussed with Mr. Vipul, he assured that he will give the replacement for the motors next day.
On 12th May, we waited whole day and got informed after several follow up that due to delay from courier service our motor did not reached service centre.
On 13th May, we were really lucky to get the replaced Motor only to discover that the problem was not with the motor but with the connection circuit. But this time we probably had the best engineer and he fixed the problem and the Cooler was working. We were really glad to see our Cooler working after 7 days of purchasing it.
On 15th May, we discovered, this time the cooler is throwing hot air and we cannot listen to the sound of water circulation.
On 16th May, once again I registered a compliant (Compliant No. 16/2) at your Service centre and when talked with Mr. Vipul, he assured the serive will be done on the day itself. This time we were aware of the fact that the next day is Sunday and I can get only promise delivered in that day. But nobody came on 16th.
Only we receive couple of calls from Service centre on 16th and 17th May to confirm our address.
On 18th May, after calling several times at your service centre and Mr. Vipul only thing we received is assurance.
On 19th May again we received assurance from Mr. Vipul and Service centre after number of follow up calls without any solution and no service engineer visited our place.
What can I do next to fix the issue?
