Rude behaviour from a "Customer service" employee

Saturday the 11th around 10:00 am, I was at Cell C in gateway to have my SIM card unsuspended as I was previously advised I could do so, upon entering the store, I was greeted by an Indian guy that works, it's a pity I didn't get his name, so mom and I sit down and start explaining what we need help with and right off the bat, his rude, he cuts us off and by saying "I don't think we can pick up that cellphone number if it was contract with a store" I explain that I have been in this store before and two gentlemen explained what I needed could be done, I just needed to come in with my mother as the contract was previously in her name, he proceeds to totally ignore that ,after some time takes to mobile number and it appears on the system, asks for numbers I've called before, as doing a simswap of which is not what was requested from him, he further proceeds and says the numbers I've given fail security check and I need to call customer care but I need to buy a SIM card from him for R5 and before I could ask any further questions, his on his phone, mind you my mom and I, are not done asking him any questions and he is unbothered about assisting us any further.....even the 1 star rating is not appropriate for the way this man disrespected us and clearly was not in the mood to assist, I've been a customer of cell C for years and I've never received such appalling service, very disgusted.
