Unhappy client

Hi I've been to sars twice ,updating my documents ,updated new banking details ,at two different counters ,here in Paarl ,I'm frustrated cause I haven't received my refund as yet ,the first person said : 72 hours ,second said : 21 days .it's not fair how u being treated as a South African law abiding tax payer ,why should u go to sars twice ,and the problem next sorted ,u sit in long queues....the sars efiling app ,doesn't recognise my credentials.this is outrageous!!!!
