Nedbank Send imali Service disappointed

I have mistakenly sent money to a wrong number.

Being calling the call centre to cancel the request and have it back in my account but no one willing to help me with that

Instead offering my credit cards and loans.

I know it's my mistake but it's my life on the line.... My studies basically if I don't pay i don't right my exams and wasted one year of my life

I want to cancel theNedbank Send imali Service and return my money I can't wait 7 days that's too it's not granted too
