Indian Overseas Bank — harassment

Address:

695146

I’m a medical student studying in russia,
Today 12/02/2019 my mother went to the iob bank for changing an atm cards ownership which has been formerly on my fathers name to my mothers because my father is working abroad both have a joint account there, so the bank authorities told her that they could change the ownership of the atm to my mother by mailing them which should be done by my father. Like what they said my father send an email regarding the changing of atm card’s ownership. After some days they called my mother today to come and collect the atm card which is been renewed to my mothers name, and she went to the bank for collecting the atm card and the she got harassed by the bank manager there. They harassed about the request that have been sended to them saying that the english used for email was poor and ordered her to send an another email and only after that they could handover the atm card to her. Both my parents are using their account at this bank for more than 10 years nobody have been like this to them since they started their account there. I hope you understand about this situation here and take necessary action towards this manager there. And surely we will deactivate our account there and kindly make sure that no more customer should be harassed like this because of their literacy or anything and don’t make them run like this.
