Say:

Don't worry

or

Don't be worried

As for the second part of that sentence, I don't see how it goes with the first part of the sentence.

As for the second part of that sentence, I really don't know how it goes with the first part of the sentence.

Possibly:

We will forward the report to the relevant colleague or department, but we would like your assistance in handling the matter.
