Worst service and incompetence by employees

On Saturday I decided to apply for a fnb unlimited sim card at boksburg branch which offer unlimited calls due to Vodacom technical problems. The consultant helped me n couldn't do a sim swap n she said I must do it myself . they debited R600plus ,we inserted the sim and she made mention it will be activated after 4hours so I waited ,to my surprise the day ended n nothing was happening tried numerous times again nothing today I decided to go to the Tsakane branch they connected me with the mobile dep ,I explained the issue they couldn't help told me I should wait for a max time of 3days for support .the support dep called shortly I thought help was finally here to my surprise the guy could help said he will call before 17:00 today,he didn't return the call .I've paid R600plus just to have a sim card that can only send call backs .when I ask them about compensation the guy says we will discuss .so much for trusting a bank to do better .poor service and incompetence at its worst .Fnb n Vodacom must close shops if they don't know what they doing .
