IDFC Bank — Amazon Pay Later Auto Debiting More Amount than Original Amount

I am using Amazon Pay Later. The IDFC bank auto debit more money in the place of original amount. Transaction statements not showing proper way. What is EMI amount, what is normal amount not showing. Some amounts not converted to EMIs. In March transactions around 13K used. But in auto debit it shows 18k+. Nearly 5k+ transaction error. May be same transaction errors occur in previous transactions. Correct the transactions errors immediately and refund already debited amounts.
