Query: Did not work for me. Difficult method in communicating with the seller. RETURNed!

I had high expectations about this charger. I already have four wireless chargers so I already know what to expect from another wireless charger. From the product description, this should be the fast charger I am seeking for my iPhoneX. First off, when I received it, the packaging was very plain in a brown box. No problem here as I know it's about the value and packaging is going to be thrown away anyway. Secondly, I swapped out my Kroma wireless charger with this one. I actually have a RavPower and Anker wireless charger in the house as well. When I place my phone on the charger I look at my screen to see if it's actually charging. After the first night, I woke up with my phone still at 60% of power. WTH??? I gave it the benefit of the doubt so I tried again and the same thing happened. I swapped out the AC/USB connector and the cables and the charge rate was either nothing or negative but the phone still indicated that it was being charged. I contacted the seller directly and they asked me a few questions like do I use a case, what kind of phone I have, do I have a metal plate (for car mounting), etc... I answered very awkwardly because there was no easy way to reply except asking another question on the order page on Amazon.com. So I answer the questions then they say, try charging the phone without the cover and plate. I did and I still have the same results. Then I tried to let them know that I still cannot charge my phone after and I run into a virtual wall in communicating with them through Amazon. There was no easy way to get in touch with them! All of the communication from them was via e-mail with no way of replying in e-mail! I've been doing this quite a bit and I'm an Amazon Prime original member so Amazon.com has done well for me. I just submitted a return request because my iPhone X with the case and the plate did charge properly with ALL of my other wireless chargers. Thus, regardless if this worked with or without the case or not, I'm not going to use it if I have to remove the case every time I want to charge it. I'm just going to return this. I don't want an exchange now. I do not want an exchange simply because I have used similar products and know how this should work. The seller tried to help me but I'm just not happy with this and I'm not going to give it a second chance considering that I had such a difficult time communicating with them and I truly did not get a sense of sincerity. I may be harsh on this review but with all of the competition out there with the same products, these sellers/suppliers needs to get it right and act fast if they want a believer in their product. I've had other companies send me an exchange on the same day with no questions asked. I'm hoping I'm the only one out of all of these 5 star reviews who got the fail. I can truly question now, are all of these reviews real or not?
