İf you would refused to give that phone call what would have happened ?

Thank you.

eğer bu telefon etmesini kabul etmeseydin ne olurdu

my try

do you mean ´if you had refused to make that phone call what would have happened?´?  I think elenagabriela has translated as ´if you had not accepted that phone call.....´ which is quite different 

O telefonu vermeyi reddetmiş olsaydın, ne olacaktı/olurdu?

Thank you all.

she says "phone call" so I don´t think she means to give away a phone, which is meant by the above translation.

If you would have refused to make that phone call, what would have happened?

Ok, it was a quick translation, I had not seen the the word "call" there,  just realised now when you pointed out. By the way i guess no need to change the English sentence "to give a call" fits the sentence quite well...

It was not clear for everyone
