Poor customer service

For 4 months now I have been sent from pillar to post by Samsung. I have repeated my story on so many accounts to so many different people and to date I have received no feedback or assistance. I have never had such a bad experience. It has come to a point now where my household has decided that we will not continue with any samsung product. My Husband who is a huge a Samsung fan has now decided to upgrade and chose a 1+ due to the poor service I received. I upgraded my phone to the Samsung S 20 ultra and with this promotion I would have received the Samsung buds. My IMEI number did not register on the Samsung App and I reported this to Samsung. To date I am still waiting for the escalation department to call me back. This department is never available and I am always told that they will ensure they call me back.
