Dude dude.. Chillax man.. Obviously, you are not a Singaporean & bargaining for RMAs in Singapore. Got a thick enough skin to RMA 3 times..
I can bet $20, put in envelope meet at MRT station if you win, that out of all 3 products - you did not RMA because of a faulty product. There is no way to know the truth unless you are honest, which blah.. I think not.
Your customer attitude will make anybody in the service industry disgusted, and will refuse to bother themselves with you anymore. You can't do anything to them because you are too small. You can't boycott them because you are one of a kind cheapskate.
So one advice - LLST (Lan Lan Suck Thumb)
Keep quiet.
Go ahead & Buy Logitech.
Your $20 is cheaper than a bull-log chart-wheel! Who are your witnesses and judge. I bet you high stake $100,000 to cow your arrogance that I am not a Singaporean. I win and you'll lose.
If there's hardware warranty, that’s customer’s choice of satisfaction. Therefore, it is not cheapskate. That's why we have CASE and lemon law in Singapore? So you call me a cheapskate because I RMA whereas MS Support did not say.
MS Support had genuine accepted that the mouse was spoil with RMA approved. But the delivery was with the wrong mouse. The correct Sculpt Comfort Desktop Set was not delivered and it is different from the wrong delivered Sculpt Comfort mouse standalone (Bluetooth)?
Because of MS Support wrong delivery with the wrong mouse, MS do not want to bear any further delivery cost to take back the wrong mouse and to deliver to me the Sculpt Comfort Desktop Set. So they want you and me to bear your own cost by making wild allegation with their "APOC End User Fulfillment Program" and to go personally down to 438B Alexandra Road.
I hope not to repeat the same answers many times. Maybe you did not read and to understand all my statements.
