Customer Review Policy Violation - ASIN blocked

Hi,
2 months ago my ASIN was blocked due to a policy review violation.
Since then I have been trying to get the ASIN unblocked but no luck and the only thing I get is the automatic email with the bellow request:

To remove the warning and restore your listings, please send us the following:
– A detailed description of all methods that you used to post or obtain customer reviews that are prohibited by the Amazon Customer Reviews policy.
– Contact information such as name, email address, and website, of any third parties that you engaged to obtain prohibited reviews or manipulate reviews.
– Identifying information for any customer accounts that you or a third party used to post prohibited reviews.
– List of any prohibited reviews that you obtained. Please provide 1 active review IDs or review links of those reviews. Review ID example: RVBTR9XXXXMM. Review link example: https://www.amazon.co.uk/gp/customer-reviews/RVBTR9XXXXMM
– Documentation such as emails or receipts from any such third party confirming that you used their service.
– A detailed plan that explains how you will prevent customer reviews manipulation in the future.

I have not used any 3rd party tools. The only thing I can think of is that out of the 20 reviews I received 3 were from friends.

I stated on my response the 3 reviews from my friends together with their verified purchased order. That was 100% legit as that is the only way they could have bought the product as I do not hold any stock, and they decided to write the review with their experience.

Is there anything else I can do to unblock that ASIN and sell it again?

Thanks
