Bad attitude and poor service by a clerk

Went with my friend as he needed to replace his atm card which the machine in Roodeport had swallowed. After having gone to two branches that were SUPPOSED to be open on Sunday from 9am till 1 pm as advertised on website and on their doors and they were not. Hence we were already very irritated as we had to travel so far to get this sorted. My friend tells the clerk that he is really "****ed off" and that he just wants to get his new card and get the hell out of the branch. The gentleman clerk (Lena) then said he refuses to assist us as my friend is swearing at him., which he clearly is not. How the heavens will this clerk of yours deal with a irate or irritated foreigner that has just come off a 30 hour flight, is beyond me. I am DISGUSTED that you could allow someone like that to deal with your clients. I think an apology from the clerk is definitely forthcoming and he should not be allowed to deal with clients going forward if he cannot take the pressure.
