SMG ARC POOR SERVICE,RUDE EMPLOYEES,INCOMPETENT

My vehicle was authorised for minor repairs by my insurer in 2018.One of the mag wheels was scratched and SMG ARC had the mag wheel repaired by wheel collision.Ever since the repair normally every year the repaired mag wheel starts fading and the clear seems like it's melting.I contacted SMG ARC and informed as I do yearly of this problem I was transferred to a rude person Viresh who says I must now ask my insurer to replace this mag wheel eventhough I have since changed insurers and it is now 4 years later.I spoke to Hennie the GM there and he confirmed that he cannot find any trace on his system to confirm my vehicle was ever repaired at SMG.I called my broker and they sent me the authorisation letter and the quote that was done by SMG I then forwarded this to SMG.I got a call from my broker stating that Viresh was calling and asking questions relating to my insurance which I never consented to.Viresh called me and I told him he did jot have permission nor consent to speak to my broker and I asked him if he was aware of POPPI ACT He stated he can speak to whoever he wants to,he was arguing with me and I asked him why he is rude.Viresh then stated to me that he will make sure nobody at SMG ARC will assist me because I think I am too clever.I have since lodged a complaint with BMW SA,how xan SMG ARC be so incompetent and have such rude and incompetent employees....Stay away from SMG rather go to Supertec.
