Samsung A70

I have had problems with my Samsung A70. My phone was purchased in July 2019. After 5 months of having the phone, my phone did not want to charge. I then had to take it into wefix to have it repaired and based on a small scratch on the side of my phone due to my cover, my phone could not be repaired under warranty due to "drop damage" as they call it. I was then charged R550 to have my phone repaired. My phone was at Wefix for just over 2 weeks when initially they said 1 week. After getting my phone back, not even two months goes by and my phone does not charge the same (I charge my phone with the original Samsung charger that was given with the phone). Each time I charge my phone it either chargers super slow or chargers down (from 5% to 3%). If my phone is completely flat and I try charging it, the phone won't go back on till I tried using a sumsung A30 charger. About a month after that my phone again did not what to charge and now it won't go on at all.

I tried calling, and the call center assistant said she cannot help, I need to take it back in to wefix to have it fixed. Which means I would need to pay AGAIN.

Samsung keeps shifting the blame without taking ownership on their defected phone.

I took my phone to wefix more than 2weeks ago and I still have no feedback as to what is happening with my phone. I have no response to what the issue is or what it has been. Please can someone respond to me with an update
