My Client Just Called Me A Scammer, What Do I Do?

So this past client of mine works in the E-commerce industry selling latex pillows; however, he doesn't sell a variety of products only this one product. Now when we first began talking I explained to him that SEO is a long process and could take 6+ months to really see the results come in especially when competing in a competitive industry with larger companies. Now at the time he had agreed with me and said he was ready to get started which I figured yeah let's do this.Almost immediately he began micromanaging me trying to intervene with my process SEO at every turn by saying things wouldn't work or saying how he doesn't believe that's a good idea. Now many people would be annoyed by this seeing as if he already knew what works and what didn't he wouldn't be hiring me, but in most cases, I just see this as a client being involved with their business and just shrug it off and try to work with them as much as possible.Then one day I received a text saying "Hey Justin, I canceled all other forms of marketing and we will be relying solely on SEO right now" this took me as a complete shock and I informed him that probably isn't the best idea as the best marketing strategies don't rely on just one channel but rather multiple feeding off of each other and if he were looking for money immediately SEO wasn't going to do the trick. This fell on deaf ears and no more than a week later he began to become more impatient saying things like "Hey sales are down this month" or "Hey I think we need to pivot our SEO strategy" and while these things may not sound crazy it had only been 1 month at the time and I had just laid the foundation and redone his website to fit the strategy I had laid out so essentially we never even got to try it out.Fast forward to the very next month and I get another message saying "Hey Justin I spoke with another marketing expert and they said it would a dumb idea to continue with SEO services as they don't belong on an eCommerce store. You may have not known that but maybe now you won't scam people in the future." Can't lie this hurt a lot as I pride myself on providing quality SEO services to the businesses I work with and I've worked and currently work with both service businesses and eCommerce stores in the past that have seen great results. I ended up just replying with "No problem, best of luck to you" but am I wrong here? I told him everything I could and didn't even get a chance to see my plan come to life then was dumped on for it. see hubwealthy.com/wealthy
