Vodacom After Sales Service SUCKS

On the 11th of November i upgraded to a Huawei Mate 20 Pro, and out of the box the phone had a display fault. i returned the device within 7 days and they advised me that the device have to be sent in, evaluated and then a decision will be made. After long arguments Vodacom gave me a new device, Within the first few days i realised the new device has the exact same problem. Trying to speak to Vodacom, i am simply being advised that the same process must be followed. Since i live 85km from where i upgared, i have to constantly drive up and down to hand in the device, and drive back when collecting. In this time i also have to be without a phone until they decided what to do. Calling the outlet, Vodacom Customer care, Vodacom Repair centre, No one attempts to help me. but putting their shoulders up telling me i have to follow procedure. I am Paying R800 a month for faulty devices i cant use..
