Unpleasant MobiMoney service

The Nedbank branches have disappointed me consistently for the past 6 weeks. My sister sent me instant money to keep safe for her and since then it has been a mission trying to retrieve the money from their money apps. If it’s not a case of network problems it’s a system problem which non of their employees understand themselves.They have confirmed that the money was sent and that I should have been able to withdraw it immediately, however due to a lack of knowledge by the employees as well as the consultants they called at their head office we’re still without our money. In all honesty my greatest displeasure is the lack of emergency and knowledge that the employees failed to display, I am very unhappy with their services.
