Samsung VOC Department a disgrace

I took my Samsung S9 in for repairs to SSS Cellular in Boksburg who is an authorized Samsung mobile repair center. The Technician formatted my phone and essentially removed all the preloaded app's - some of which make the S9 unique. After the repairs, the firmware was updated to PIE and a handful of app's were installed - not half of the preloaded app's I use to have on my device. So bad that I had to download basic app's like a calculator, not to mention outlook... Now you don't need to be a Rocket Scientist to figure that I've been shortchanged but neither SSS Cellular nor the Samsung Call Center understands my complaint and I have been left dangling in mid air for more then a week now - with no solution in sight. I have a "supposed" high end phone that is no better than an A3. In fact, the A3 comes preloaded with a calculator... The feedback essentially is that I now need to download "freeware" from play store in an attempt to get my phone back to the state it used to be. "Sorry Sit, it is the new firmware" Is it fair to expect from me, the loyal, PAYING Customer to download freeware as a result of incompetence at a Samsung Repair Center? Not to mention the adverts and popups and **** that come with these downloaded app's. Is this what I have bought in to? Is this now the service that can be expected from Samsung after you forked out an arm and a leg for a high end Samsung Galaxy device? All I'm asking is for my phone with its preloaded app's - the way it used to be. Surely PIE does not uninstall app's.....
