‘Can I call back to you after some time?’ -Is the sentence correct?

Anonymous

So I am an Asian Lady and not good in English. Yesterday I call came in my corporate number from an expat and I had to answer the call while I was in a elevator. His voice was not clear and this is why I told him that can I call back to you after some time?

The elevator was full and people were staring at me while was talking. Is it a wrong sentence? I am feeling very ashamed.

Please help!
