HDFC Bank — Deducted amount as mctf

Not able to understand why an amount of rs 8, 000 suddenly deducted on 2nd june 2020 in reference to 30th may 2020!
On 30th may tried to withdrawn but the atm was running out of money of rs 200 so it first debited and credited! But again with mctf reference deducted rs 8, 000 on 2nd june. Please return the amount.
