Titan Company — replacement button cell for my titan wrist watch (model no.162 yaf)

Address:

World of Titan, Besides Swagath Hotel, Near Ganagaram Hanuman Temple, Chanda Nagar, Hyderabad-500050, Hyderabad, Telangana, 500050

Dear Sir,
On 12/04/2019, I visited "World of Titan" Titan watch show room at Chanda Nagar, Hyderabad, (address given below) as I wanted to replace battery (button cell) for my Titan wrist watch (Model No.162YAF).
I have been using this watch for the past 15 years, having received as a 20 year long service award from my Employer (L&T). In the past, many times I changed the battery, but till recently maximum price I paid was Rs.78.00 only (I have all bills for the batteries replaced so far).
But this time, to my surprise, the show room service person demanded Rs.173/- for the battery replacement, and he said it is company system price. (Invoice attached).
In the invoice, there is no any mention of the battery model no., breakup of part price and service charges, and no mention of warranty, which normally given in all other previous bills. I felt it is a kind of cheating customers by the show room and I request M/s TITAN to review this matter.

Thanks & Regards
M.Pardhasarathy
