Foreign Exchange bad experience

Having just returned from overseas, I proceeded to exchange my foreign currency at the ABSA branch in Woodlands Boulevard where I had initially done my foregein exchange transaction. The customer care lady at the entrance told me that the man who deals with foreign exchange is not at work (apparently off sick) and not sure of his return date. When I asked her if she can call him and ask when he is back, she shrugged her shoulders and told me he had sent a message only and not answering his phone. When I asked her if there is no one else who can assist me, she rep**** no one else can assist and suggested I do my foreign exchange business at Menlyn Maine (which is totally out of my way) instead. Really! I would have expected a big bank like ABSA to have backup plans and people in place should someone be off sick and also person who is sick to have the decency to tell his employer of his expected return date! PS. Just so you know, this is not the first time. Many years ago when I returned from overseas, I then was also turned back as lady then who dealt with foreign exchange was on maternity leave! This was at ABSA in Northgate Shopping Centre.
