Liberty Shoes — Crack in Sole and After sales

Hi, I am Dalip sharma, I have bought a leather shoe from your Uttam Nagar Show room around 1.5 years back and wore it around 4-5 months occasionally because of work from home. Now i used it regularly from last 1 month and the sole cracked like some cheap shoe.
When i bought the shoe the salesperson told me that Shoe and its Sole of this shoe is of best quality and if you get any issue we guarantee that and now when i called them they said its normal if we don't wear shoe everyday the sole used to crack which is such a bad statement. Even when i asked to get the sole change he said charges are 800 but it takes 3 months.
Why would i buy any liberty shoe ever. I thought i bought a Best product but sadly it was the worst.
