Staff needs Telephone Ettiquette!

I called the Randburg office yesterday 14 November 2019 to advise that we need a new black toner. I spoke to Nomsa who advised that it can only be delivered today 15 November 2019. After receiving the toner I then proceed to put it into the machine which gives me an error that " the black toner must be set correctly", I then called Nomsa back again who assures me its the correct ink and that a technician might then need to come and have a look. She then tells me she needs to refer me to that department. I then speak to a lady by the name of Lerice Hollander who immediately becomes annoyed when I asked her when the technician will come. I understand that she cannot give me exact time, but she didnt even make an effort to find out how many clients the technician should still see before assisting us. While confirming with her colleague she just puts me on hold without warning and comes back to give me information. When I tell her that she then blatantly lies and says she told me to hold on. The customer service is pathetic at Nashua! There is no regard for the urgency of the matter. Their is a lack of problem solving s****s from the staff let alone their inadequate telephone etiquette as I called back again and another lady just also put me through to Nomsa without warning!
