Yes Bank — failed pos transactions

Sir, on[protected] morning i used the yes bank titanium debit card in the merchandiser khivraj bajaj pos swipe machine for 2 transactions (Pca:[protected]:khivraj: 57, 322.00) (Pca:[protected]:khivraj: 30, 000.00) to purchase a bike but no debit conformation received from the machine and also i got the sms debit conformation on my mobile after 20 mins only so the two transactions amount of 57, 322 & 30, 000 has been debited from my account but not credited to merchandiser khivraj bajaj account so by that day itself contacted yes bank and raised (Customer (Transaction) dispute form) and when contacted yes bank customer care they say the maximum time taken for resolving this problem is 60 days. And afterwards i have arranged the cash from other source and bought the bike but still now the amount has not been credited to my account.
My question is why so many days it is not a small amount 87, 322 in total is a big amount for me and i need to take care for other expenses and only one person involved in this transactions khivraj bajaj so why so many days required for solution from yes bank
So kindly give the solution to this problem
Thanks & regards
