Oppo a53

Good day,

My oppo A53 has a problem using other chargers to charge, I have used more than 7 different chargers (cables and charging blocks) other than the original oppo charger because it only came with one charger, sometimes when you travel you don't have the original charger that came with the phone on hand. This is a huge inconvenience as I use my phone for work as well as personal use. I have contacted Vodacom where I bought my oppo cellphone and they seem to not be able to get hold of another original oppo charger, I have found one on takealot for R999 which is not cost efficient.
