Indian Overseas Bank — Sms alert not coming to assigned number wrong account number coming

I have given the complaint regarding non availability of sms alert to my mobile number. My sb account number is [protected]. My mobile number is getting wrong account number details of operation instead of my account. I suppose my operation is being diverted to another mobile number where in my privacy is at stake. I have already given a written complaint to my branch on 28.04.2016 regarding this. I am already getting anonymous calls for which i do not know how they got my number. You will be fully responsible for any untoward incidence happens to me due to your negligence in service.
