Pathetic service

I visited the nedbank branch last week Thursday 18 January to update my cellphone number. The consultant at counter 12 who assisted me made a copy of my id and i signed a form which she printed. Today 23 January i tried to do a payment online only to find my number has not been updated and i have not been receiving smses after each transaction. After calling nedbank head office they advised me that the transaction was not done. Furious i drive to the branch only to find that the consultant is off and i need to sit in a queue again to do the transaction, i walked out as i am not prepared to sit in a queue once again due to *********** people not doing their job. This is a major inconvenience and this is NOT the 1st time complaining about the branch. They are pathetic and do not seem to want to assist customers. Why must one struggle like this for a SIMPLE TRANSACTION!!!!!!
