Shocking service from Vodacom Repair Centre

I have received the most shocking service from Vodacom over the past almost 5 weeks. I have been a Vodacom customer for approximately 25 or more years and spend a considerable amount monthly with them. On 8 December 2022 I handed in my son's Iphone (which is still under warranty) for repair at Vodacom Cresta. I was advised that the repair would take a maximum of 2 to 3 weeks, at worst. After 3 weeks I started following up, only to find out the phone has not even been assessed and have been sent back and forth from one repair centre to the next. My son was also asked to again deactivate "Find my Iphone" and a new job nr was logged after 3 weeks had already passed. I followed up basically daily thereafter, however still don't have any positive feedback, I am just being advised "the technician is busy assessing the phone". The absolute horrific service experience has left me shocked and I will definitely not be a Vodacom customer in the future.
