Vodacom repairs is useless

Another pathetic experience with Vodacom :D

I booked my cellphone for repairs under warranty on the 7th of May 2021. The device is still under warranty and was repaired. The device switched off and did not want to switch on again. The pcb was replaced and sent back to me. I received the device and started using the phone again. When I set up my security information and passwords, the fingerprint sensor did not work. I did a hardware test on the device and the fingerprint sensor failed. I got this error message: 'Contact Customer Service". Are they not supposed to test the device after repairing it, before sending the device back?! So I booked in the device for repairs a second time on the 22nd of May 2021. Today is the 7th of June, 17 days later and I have not received any info about my phone. I contacted the repair call center and was promised twice that some manager will contact me in 24 hours about the issue. I am still waiting to be contacted and a few days have passed already. I asked the people working at the call center what the issue is. They told me that the pcb and 2 other parts are being replaced. The pcb was replaced just a few days ago?! I do not recommend Vodacom to anyone!
