Vodacom Chatz - Wilrogate - Poor service, unprofessional unacceptable conduct.

5 - 28 March 2019, the cellular phone was in and out with this supplier for repairs. Paid for a new battery but the phone remained a problem - every time another explanation and work to be done. Why was the phone not properly checked the first time? On 28 March, the phone was returned without its SIM. Upon enquiry as to what happened etc. because I was now very frustrated and worried, I was shouted at, the phone was put down in my ear and then Daryl Clifford went on to throw stuff around in the shop and shout at his staff in front of customers (including my mother). Is this behaviour acceptable when you made mistakes and are asked to explain by a customer? Vodacom really should select their people more carefully and provide training on customer care and general acceptable behavior.
