Address: 401203

I am vinayak apate mtcn number [protected]. I gave wrong account number it's my fault and they deposit in that account but with that account number i gave account holder name. If given account number and given account holder name is different than how come they deposit in that account.
I ask western union how they deposit the money in that account buy they said it's already successful transfer to account
We can't do anything u have to contact bank
Why should i contact bank i gave money to western union so if their is any problem i have to contact only western union
