Affiliate Marketing Secrets

I just had a terrible experience with a company who laid down vinyl flooring. I asked that they come and tear up the floor and refund my money. They have honored this request, but are making me sign the below waiver. They tell me that me signing this waiver removes my right to post about my experiences with their company on any review website. Could any of you read this and tell me what provision of this waiver unambiguously states that I am not allowed to publicly share my negative experiences with this company in a public forum? Remember, it cannot be considered ambiguous. Thanks.
