Canara Bank — Providing worst service my mobile number not updated not picking landline call

Address:

Madurai K.pudur branch

I had given request to update my pan card, mobile number and email ID update they told it will take 2 working days it is been passed and I called customercare the executives dont know the process they told it will take three working days
they gave me branch number Im calling but they didnt pick my call.

i need to change it asap and also the lady in K.pudur branch is very rude to me because Im not holding any balance in the account for long time

she can tell me politely or she can follow as per bank procedure I dont know why she treated me like a begger which I dont decerve
