"I have Purchased Hummer Miner H1 Device…"

I have Purchased Hummer Miner H1 Device from your Company.
I received it and hardly used it for 15 minutes. One of the hashboard caught fire.
Since 3 days i am trying to claim for replacement. They are forcing me to pay for courier. The made me work like a technician and pull out the hashboard which caught fire.
The Order was place on June 19 and was informed that i shall receive the package with in a week time.
But i received in on 7 July 2020 which made me loss. As in crypto market time is essential.
Now they are refusing me to send it through courier.
Kindly help me resolve the issues.
They are now saying that they shall provide send me one hashboard only if i remove the review. They only want good review and not bad review.
I shall remove the complaint only if you agree to ship the miner to me. I am not ready to bear another further cost. The machine is surely used machine as the warranty seal was broken and some one else miner pool details was found inside.

"I am usually not one to write reviews…"

I am usually not one to write reviews but, in this case I want to share with others of my buying experience with Crypto Miner Bros. Being in Seattle WA, I was very uneasy about buying from a Hongkong based company other than the Manufacturer (Innosilicon) directly. Sending large amounts of money internationally to a company I have never dealt with was making me a little nervous.  However, after reaching out to Crypto Miner Bros. through What's App, I was able to speak with Andy from the company over the phone. Pretty soon, I began feeling comfortable about placing an order, not only because I could reach them directly but it was the manner in which they handled my inquiry that really impressed me. Extremely professional and took the time to explain to me in detail what and when I can expect from start to finish. At no time did I feel pressure from him to "buy now". At first I placed a sample order. The miner was shipped within 48hrs. from Hong Kong and arrived at my door in Seattle USA 3 days afterwards by DHL  just as they promised. Crypto Miner Bros. made the whole process very pleasant and easy. Several days later, I placed a second order, much larger than the first and those miners just arrived 2 days ago. Also, just as they promised! i am so much extremely happy and satisfied customer, especially considering all the things that could have gone badly with this type of international transaction. I would very highly recommend Cryptominerbros to other users of your website based on my experience with them. Thank you!
