HDFC Bank — bank account

Address:

401303

I submitted a mobile changing form last Thursday ie on 31st Jan 2019.But it's still not been done. My new mobile number is [protected]. I have the receipt. It's yet to be done

The bank has debited my account twice with RS. 286 against some one EMI charges but I don't have a loan nor a credit card. I repaid the Gold loan last June 18. I have attached the screen shot.So why such debit?. The bank has charged debit card fee whereas mine is a salary account there is no fee for debit card. Can you please explain.
