Cannot access data on My Passport portable 500GB

Hi - received the following via e-mail:

Thank you for contacting Western Digital Support.
My name is [[Deleted - Trancer]].

I would like to apologize for all of the inconveniences which you experienced with our product.

Unfortunately we do not have enough information to provide you assistance.

Could you please provide me more detailed information about the problem which you have?

As soon I will receive required information we will be able to provide you further and more accurate assistance.

Have tried to respond but address not valid so this is my question:

Not sure what other information you need from me. I have explained what difficulties I am having, i.e. there is definitely data on the My Passport drive but all of what should be there cannot be viewed if it was filed in a sub folder.

If you could be a bit more specific about what you need, I will try to provide it.
