Makro pathetic service

On the 21st of Feb 2021 i purchased a cellphone at Makro's Germiston Branch. Today 24th Feb (4th day of the 7day replacement policy) I returned the phone (Samsung A3) to the store as it was giving me problem with touch screen) The sales consultant Nthabiseng Khitsane was unprofessional in a sense that she even indicated that she is not a technician when I explained my problem worse over Makro's Wifi was not working in order to elaborate and show my query. I then requested someone senior, lo and behold I then spoke to Ross Smith (General Manager) who I thought would understand my query. I also hit a brick wall. They both told me to take the phone direct to Eastgate Mall Vodacom Tech Centre. I get to Eastgate and the technician lady tried to phone both Ross and Nthabiseng they were not available apparently they went for lunch. What irks me more is that I was not supposed to travel to Eastgate according to the lady technician, instead the two Makro employees failed to follow the simple process i.e. Since my phone is less than 7 days the OBF process was supposed to be followed. I wasted my time and fuel of travelling unnecessary and feel ******.
