Horrible service Telkom

I have called Telkom 5 times this morning as I want to top up my WiFi. I am writing an exam in the next hour and no one can tell me how to top up my account. The line cuts and no one gets back to me. I’ve been told to call 10210,10213 and 081180 but no one has helped me. I even called and the one agent was chatting in the background and I could hear everything but no one was attending to me. I held for 4 minutes screaming hellooo! But she carried on with her chat. I have had this contract for less than a month and I regret it. I wanted to get a phone contract with them after getting the WiFi and they declined me saying me my credit rating is low even though it’s above average. How do you give me WiFi but decline me for a phone the very next day? When I ask what is the rating they have they said they can’t tell me that. Telkoms customer service is horrible. I would not recommend it. No one has contacted me back and I don’t know how I am going to write this exam.
