Worst Customer Service ever!!!!

I Ordered a xiaomi S10+Robot form FNB. The Robot is Faulty and I phone FNB Customer Care and they told me to Send Pictures of Faulty Product then they will send Courier. I did send the Pictures the same day and phoned Numerous Times 7 Days Later still No Response. The Lady from FNB just told me System is Down she will phone back and never phoned me Back. Today when i phoned them again i spoke to a Gentlemen who was very Rude and actually got personal when i told him that it is 7 days and that i am fedup. I have never in my Life experienced such unprofessionalism from a Person. I have again sent Numerous Emails Requesting for manager to phone me. FNB still have not responded to any Email. I am Private Wealth Cuctomer at FNB and thinking of moving over to ABSA as i have never in my life been treated so badly.
