Pathetic customer service over the phone

Polmed customer service is pathetic and unprofessional a lady called Karabo assisted me and she had absolutely no clue of what she was doing making me hold over and over confirming everything over and over, then to top it up kept saying in a condescending tone on the "lower plan that you are on"as if am not paying for it,when I adressed it she kept saying that she does this everyday and tells peoplw everyday that they are on lower or higher plans...well just because she does it everyday does not mean its correct, how about she refers to the name of the plan instead of referring to it as hig or low, she apologised only on the 3rd attempt, I seriously have an issue with unproffessional telephone etiquette and have never encounted such rude behaviour over the phone at polmed, can such behaviour be adressed and can customer service training for Karabo be more improved!!!!!
