Bad customer service

Staff at Maluti cresent are bad at customer service, they don't know what client experience mean. I went to the store to do a sim swap and I was told to bring the proof of residence after queuing at the atm for the statement I went to the store at 13:50 and I have the door closed they told me to come the following day of which it does not make sense to me because the store close at 14:00 and the staff is still in the store and I have to travel all the way to harrismith for such service.. not happy with the service
