Vijay Sales — bad customer service experience

Address:

Mumbai City, Maharashtra

Recently i had purchased a faber hob from vijay sales in mumbai. Which during installation at my home town was noted to be a faulty product as the ignition was not fitted properly. I had registered a complaint regarding it saying i am entitled for a replacement of product and not repairment as its unused. They responded that a technician report is required for any further process also extra charge will be taken since its outside mumbai. So i bought the unused product back to mumbai and it's been about 15 days and no technician has been arrived to check the faulty product.
I daily connect to their customer service and now i had finally contacted the branch that i had purchased from. But still no satisfactory service is been provided to me. I had to come back to mumbai leaving work at my home town and wait for the technician to come and report to be filed and analysed. It's as to i had damaged the product.
This was my first and last time experience with vijay sales. Customer buys an expensive product from a departmental store and not online expecting a good and fast service, but guess i got that wrong.
