Worst customer service ever from Asisa at Telkom

I understand that technical issues are no-ones fault. But I believe a business has to provide good product/technical service or excellent customer service if their product has faults. Telkom provides neither, I had no network, I couldn't check balance and eventually when I called , I was told that I used 600mb the previous day, when I requested for an explanation I was told someone from the technical department will contact me with 24 hours, I asked her more than three time if she was sure, she said yes you will be called on Saturday. Sunday morning I called and spoke to Asisa he is the king of rudeness, he told me that I am not the only customer and I am not the only customer with issues. I requested to speak to his manager he said there is no manager available, I said I don't want to speak to him anymore, after arguing for 35 minutes he said a manager will call me before 16:00 , guess what there was no request sent to the manager and he said I the customer have issues. I never felt so frustrated and upset. Network was already bad and the telkom customer service are equally as bad if not worse.
