Pathetic service from Mickey mouse agents

I have been trying to call Finrite for the past few weeks and get cut off continuously. I've sent an email about a month ago requesting feedback regarding a device repair that Telkom confirmed your company had to pay for and no one had bothered to reply. I received notification of an unread receipt which I assume my enquiry was not attended to. When I tried calling the call centre again today, an agent by the name of Karabo answered the call laughing. I asked her if I could give her my reference number and she placed me on hold. Call got cut again. I called back and she answered again. I told her that she put the phone down in my face and she non chalantly tells me..I don't do that, the line got cut. Absolutely no apology or explanation. After giving her my reference number, she says, "hold the line please". I was on hold for at least three minutes until she returns to the call asking, " what is this enquiry about?". She has the ****** audacity to place me on hold for 3 minutes after i'd given her the reference number and STILL asked me what the enquiry was about? What type of uns****ed people do you employ at your company who has absolutely no telephone etiquette???? I could walk into Shoprite and get ****** better service from a till packer. Please get a manager to contact me. My number is ********** 397.
