I was at a cash deposit machine with my mum to deposit cash to pay for my dad’s taxi rental. After accepting our cash notes, the machine was not able to record our deposit details nor return back our notes. After printing a receipt that indicate the error and showing a number for us to call, the screen was reverted back to its home screen, ready to service the next customer.
Luckily my mum brought her mobile phone, there are no phones anywhere near the machine for customers to call to the helpline. Dialing 11 numbers got me to connected to an answering machine. There were a few questions that I had to struggle to interpret (due to the nearby noisy market) and some options that I had to select (or not select) in order to get to a human-friendly human.
