Samsung Never Learns From Past Mistakes

I have just recently upgraded to the Samsung S21+ 5G, and I have to just express my disappoint somehow. Being 100% honest upfront I did not do a lot of research prior to as I have always owned Samsung phones and love their product. But I really must say what a complete disappoint the S21 series is. Samsung with all due respect did u not learn your lesson with the S6 series? This S21 was so expensive number 1, number two I am now paying more for less? - the damn thing doesn't even come with an adaptor to the charger, another R800 on top of the ridiculous price. Then to see that here we go again just like the S6 and iPhone which I absolutely will not own, I now again cannot expand the memory should I need to. Which is always a huge thing for me when owning a phone. It also has no earphone jack?? What on earth are you doing Samsung? I 100% regret purchasing this phone and will never be going for an S series again if this is there future. I was very happy with my A71 when I had to downgrade and spend less. I now had the opportunity to enjoy an S series again and what a MAJOR disappointment!!! I am terribly disappointed that I couldn't have the S20+ instead. Samsung do you never learn? I don't remember the S6 lasting very long at all. Hoping you bring out an A72 will make a plan upgrade to that. Try my best to sell this nonsense phone that costs so much for nothing and hopefully get myself out of this now major bill with Vodacom over a phone that is in my eyes far less superior to its much smaller brother the A71.
