So, as the solution: the manager told me that: if the UPS confirms the goods are lost, okay, then the replacement will take place by Apple. The equivalent device was said by the manager as 13" MBP 2020 with M1 processor. I asked why, because my device was the newest one at the time I purchased, however the 2020 model MBPs are 1 year older ones as we are at the end of 2021 by the way. And also I stated that I was also planning to purchase that M1 processored 2020 model MBPs, however due to the lack of plugs like HDMI and SD Card, I decided to avoid, which was the real situation (This was also the reason why I decided to give a new battery to my early 2015.)
So in this case, I stated this and 2021 model seems better to me for those reasons, which is partially accepted by the manager. However nothing is determined 100% yet.
They will call me until tomorrow evening, if my device is really lost, then we start arranging the best option like either 2020 13" MBP or 2021 14" MBP.
I asked about any price, the manager told me that there is no price if I accept the base-level MBP replacement. I mean I will not be charged for the battery replacement process.
I guess, they told me, if the issue resolves tomorrow, they can directly proceed me a MBP 2020 or 2021, as they have in stock, surely the base-models.
