I ordered this on 8th march this product was a gift for my frnd but after ordering i changed my mood and (That i dont want to gift this board) so i emailed the selller to cancel the product! And i also contacted amazon customer support to cancel the product amazon customer support told me in 24 hr ur order will cancel after 24 hr i again contacted amazon customer care and they asked me more 24 hr so i waited for more 24 hr and after that i got a notification that seller is shipped that product,, so i contacted again to amazon customer support they told me that they will cancel the delivery of product and i will get my money back! Now it was a gift to so i cant tell that person that dont accept that package (It was a gift for someone i cant tell him that i dont want to gift you this -) then as i tired my best to cancel the product contacted everyone one but order didnt got cancelled! So after few days it got delivered and my frnd received the wrong item i have ordered (Nodemcu-wifi-arduino-ide-lua-based-iot-esp8266-development board)
My frnd received 4 small boards which are use less for him now i contacted seller and amazon customer care (Seller didnt responded to my any email) amazon customer care say they are contacting seller (I dont know what they are doing but i lost my money because of this fraud seller) its almost 18 days and amazon customer care still contacting seller and seller didnt even responded to my email, he just ignoring my emails!
