Bad customer service

Tonight around 11.15pm I called MTN customer agent didn't ask for my name. I had to introduce my name, she just asked me why I called, when I was trying to tell her why I called, she cut me and asked me what's my number. Then she said okay and kept quiet after few minutes she said hold customer so I can check, I told her almost all day I couldn't connect and I was busy during the day and she told me that's not her problem when I asked her name she started arguing and dropped the call, I called again and spoke to Nothemba I asked to speak to supervisor she told me if the call is not about my number she won't be able to help me. I called third time I spoke to Neziswa I asked to speak to supervisor she told me there was no team leader available to talk to me. MTN customer service sucks. I'm going to change this network, for other networks because they have given me best customer service so far.
