Chargers stops charging after a few months.

I have been buying apple products since 2017 and each and every time, the charger stops working after a 3 months or so. Tried to get it sorted out at MTN and I was told that I need to book the phone in with the charger. That was not an option as my phone is a necessity and I can’t just book it in. Had to purchase another charger. My husband had the same issues and any apple phone purchased had the same charger issues. Now I’m 2021, I bought 2 iPads, not even two months in, the chargers have stopped working. BOTH the chargers. I called apple and got connected to the American branch. I was told a replacement will be sent until they realized it’s not possible due to being in a different country. I was advised to contact iStore and take it from there. All iStore could do was ask me to make a booking. The soonest booking is on 13 aug. I have been battling for the past 4 weeks. We are using 1 charger for five devices because of the charger issues either Achool device. To top it all the iPhone 12 does not come with a charger just a cable. My level of frustration to charge 5 apple products with one charger is through the roof right now. I would like apple to explain to me how am I paying an arm and a leg for these products and the chargers gives up after a couple of months? With all these frustrations, the service I have received is slow and time consuming. While I wait for 13 aug, my household is in utter frustration because we all can’t have a fully charged device. And no I will not spend more money on another charger. This issue needs to be resolved and I am sure there are many out there with the same charger issues.
