Unprofessional/lazy staff

I called Vodacom regarding my router that is not switching on and I was advised to take it to a store. I went to the shop in Evaton mall, Gauteng and was assisted by Thabiso who asked me two questions and then spoke to another lady and told me their booking system is offline. Mind you, no laptop was touched or my router plugged in a different adapter. Nothing, he just told me to go to another shop and when I told him about my dissatisfaction with his response and service he was not bothered and told me to go ahead and complain after I said I will do that. He further stated that they have no turn around time for their system and it hasn’t worked for a while
