I want my airtime back.

I am so disappointed in the service I received from Cell C customer service. I spoke to Lindelani ref *** and he told that if my On Us data bundles expires I should call again. I did expire and I phoned and spoke to Nontobeko Mkhize who couldn't assist me and gave an attitude, then was transferred to Team Leader Ashney Raman who said that my enquiry will take 48hrs that I absolutely nonsense I want my airtime back. And please get your Call Centre Manager Been Pucter to do something about your guys training. M so fed up of your services. How am I supposed to do my work?
