Data recovery from dead phone?

I want to recover my data form my phone which died on me . Service centre said it was motherboard issue. I don't want to repair the motherboard as I've purchased a new phone. I didn't backup the data from the old phone. Is there any shops that can help me recover the data without repairing the motherboard. Or is there any shop that does chip level service that could repair it at a low cost? Any help is much appreciated.
