Decathlon — poor after sale service/ fooling the customer

Address:

Kottayam, Kerala, 686005

I have purchased a tredmill (Domyos) from decathlon, kottayam in the month of march 2017. It cost around rs. 43, 000/- and is having a valid warranty of 02 years. Unfortunately the machine got defective by the end of aug. 17 though its was sparingly used by a single person. On contacting the kottayam decathlon branch, the response was poor that the service executive didn't respond as per the request and convenience of the customer and the technician visited on the tenth day of complaining (11 sep. 17) though it was hardly 15 mins drive from their centre. It was found to have defect with its mother board and was taken by the executive promising to get it fixed in a couple of days.
Since there was no response, i personally visited decathlon, kottayam on 16 sep. 17 and they apologized me that they forgot to order the part from their warehouse at bangalore and it would definitely be done by 19 sep. 17. Where as no body turned up or responded and when contacted they told the part is arrived and it would be fixed. But till late in the evening no body came. On 20th sep. Again i contacted the service team at decathlon, kottayam. This time they are giving the lame excuse that the spare received is again defective and it would take another one week. When asked for the details, they don't respond to my mobile and when i made a call from a different mobile, they transfer the call unnecessary with in the centre not responding responsibly and try to fool.
