I am new seller on fiverr I got my 5th order the day before yesterday. and I started working on it when I send the Design to the buyer he said "I really like it its awesome and blaa blaa blaa" but he said "just change the font" when I changed the font he said "changed the light effect when I changed that light effect he said "mmm just add the image of microphone" when I added that then he said just remove that imaged again" and continuously he asked me 25 revisions ( order was not deliver this all happened in the order page timeline ) and after that he said this order needs to be cancelled actually he was trying to compel me to cancel this after receiving the design and get the job done without paying for it I am beginner and now I am very afraid that he will cancel the order I have spent a lot of time to make my self able to work on fiverr and this is really demotivating I dont know I could carry my career on fiverr or not if he cancelled the order please help me what should I do I have spent whole night on that project I dont want it to be cancel.

since I was promoting my gig randomly on Facebook my gig was ranking everyday even it came from page 7 to first page and I got my first order after completing my first order with five star rating my gig started deranking and went back to page 3 now I am afraid that it will go back further downward so how can I save it from deranking should I start promoting it again kindly seniors tell me.
