Samsung Sales Agent doing Technical duties.

Good day, my name is David Nkuruna and i am so disappointing in Samsung, MTN & Vodacom because now my phone is damaged because of the Samsung Sales Agent in Rustenburg who said my phone needs to be updated because it was always popping with messages saying this has stopped working. I am an MTN client but when i went to MTN with my problem i was sent to Vodacom in front of the MTN store at Waterfall Mall to go look for the guy by the name of Bertus. That is when this guy who i thought was a Technician advised that i need to do a software update which he did on the Vodacom PC inside a Vodacom Shop and now my phone keeps on re-starting by itself, went back to Vodacom to look for Bertus but he was off, then i asked for assistance from Vodacom Technician but they told me it's an MTN problem because i use MTN and they also made me aware that the guy is not a Technician but a Sales Agent which does not sit well with me because now im stuck with a phone that keeps re-starting. My lawyer has advised me to take legal action against Samsung and MTN...I will be sending this message to all the three parties so they can all start getting they house in order, First Samsung why do you let your sales agent to do technical work which he is not qualified for, Secondly MTN because they consultant are the one's that referred me to Bertus at Vodacom where they should have known that the guy is only a Sales Agent and not a Technician, Lastly Vodacom because they allow someone who is supposed to be promoting Samsung Devices to do technical work for opposition Networks using the Vodacom computers and Vodacom Data...
