Pet's World — sick dog delivered who has died in a few days

Address:

Sonitpur, Assam, 784001

I adopted one german shepherd dog from the pet shop on 29th july at rs. 16500 (Which is really a high amount). At the time when they handover me the pet, (It was 5:30 pm almost on the date) he was seemed healthy. But from next day he had diraheea suddenly without taking any bad or unhygienic foods. I and my family, we consulted with veteranary doctor 3 next in the next 7 days. Doctors prescribed good medicines and tried as much as they can to cure him. But at last on 6th august at midnight he (The pet) had passed away.
This is a really emotional for all o[censored]s in our family.
So, i am very sure and have doubt on the pet shop i. E. Pet's world, located at tezpur, assam, as they delivered me a sick gsd who already had some severe disease or had a weak liver probably.
So, i want the pet owner should give me an another healthy gsd with a medical certification or they should refund my money + all the expenses which i have beared at the time of my pet's treatment.
