Titan Company — Replacement of Strap for watch

I bought an expensive fastrack watch and the strap started shredding within 3 months. I went to the store for a replacement strap but none of them had it in Malleshwaram Bangalore ( I went to 3 store in and around Malleshwaram including the Titan service center)
When I emailed customer care, they asked me to share the pictures which I did. It took them almost a month to get back to me. Finally they asked me to submit the watch to the Titan store on Margosa Road and they would replace the strap. It has been more than a month since I handed the watch but I have not received any update from their end!
Horrible service from Titan - didn't expect such shoddy service from this company.
