Worst service in the history of service rendering businesses.

I had app**** for a 20mbps deal with Telkom and was asked to pay R700 which I, I got an sms coming that a technician will come over to install it on the 31/05/18 between 8am and 4pm. They technician never pitched and when I called telkom to find out why I was told that the technician had stated that he can’t provide me with a 20mbps line but a 10 mbps line, I agreed to it and was told I’d have to wait 24 to 48 business hours in order for them to cancel the first order and provide me with a 10mbps line. On Monday 04/06/18 I got a Call from telkom confirming my order for the 10mbps line and the lady I spoke to confirmed my order. Tuesday morning 05/06/18 I get an SMS stating that the technician will come to install my line, I asked to be off work that day so that I can be around and wait for the technician but he didn’t come, Wednesday morning I get yet another SMS stating the technician will be come and yet he didn’t come again, today I called telkom and the lady tells me that my order from a 20meg line to a 10meg line was never amended and that she needs to cancel the order and redo it for the 10meg line and that I should wait another 24 to 48 hours, I have take 3 days of my work waiting for a technician who doesn’t even have the decency to let me know he’s not coming, I even sent telkom a complain but they never responded to it. So I asked them to cancel my order and to refund me but I was told that the cancellation was done but my refund I’d have to speak to their billing department. I doubt anyone has ever received such bad service before. I feel as if I am of no value to them as a potential customer which is fine with me I mean I can’t for them to give me the same products and services as the rest of the customers, clearly they have a unique measure of who they want as a customer and who they don’t
