Frustration beyond belief!

I had the worst Experience with MTN over the last two days. Was supposed to upgrade my contract. Went in to the Westgate morning with all the necessary documentation. First I enquired if they have stock of the phones I requested, before we even started the application. Then after the application was complete, she told me that she would phone me when the contract was approved and that I could collect my phone later. She phoned me around 2 pm to say that the contract has been approved and the phones were there. When I got there, she said "Eish! You're going to **** me, we don't have stock anymore. She then continued to tell me that she would phone around and let me know when the phones are there. I texted her this morning to hear if the phones are there. She said she had the day off but asked someone to phone today on her behalf. I phoned your head office, was sent from business section to another section, back to business, and eventually got told that my query is with the shop, and not with them. I phoned the branch manager of Westgate store, she got the phone I wanted and phoned me to come and pick it up. When I got there, the other phone wasn't in the colour of my choice. They told me that since the 2nd phone is free, I should take what I get. Which to my understanding is incorrect. I am still paying for the second phone for the next two years. Anyway, I abandoned the process right there and then. It is shocking how hard you guys are making it for me to spend my money on you. And by the way, we have been business clients for nearly 20 years. Absurd isn't it. You have wasted two days of my time. You have caused extreme negative emotions. And I think I should strongly reconsider my service provider!
