USELESS SERVICE!!!!!!!!!!!!!!!!!!!!!!!!!!

I called telkom on the 29th of April to upgrade my contract, the lady i spoke to assisted me and said i will get the phone with in 5-7 working days, which would have been on the 11th or 12th of May. I followed up with them on the 10th of May whereby another lady advised the courier company couldnt get a hold of me so they send the phone back. On the 13th of May i called again to request them to send the phone again and the gentlement advised me they have send it to the back office to resend me the phone i app**** for. No news from them but i had to keep on confirming my details to them, which they accepted to continue with my request. On monday the 16th of May i called again to find out on the progress of the request as i have not received any feedback, the gentlement then assisted me very well in sending a request to the back office again to confirm with me where to deliver the phone as we are back at rotation base at work. When i called today the lady i spoke to then advised the email they have is not the same as to what i have advised about and the number they have is not what they have that is why the courier company couldnt get a hold of me, i have asked numerous times for them to correct my details but seems like telkom is to USELESS to do so or to advise you on the details they have. I WANT TO CANCEL EVERYTHING WITH TELKOM AS I DO NOT WISH TO CONTINUE WITH THEM AND WILL SEEK OTHER ASSISTANCE WITH A CELLPHONE PROVIDER AS THE LADY I SPOKE TO ALREADY CONFIRMED THEY CANCELLED MY CONTRACT ON THE 18TH OF MAY AT 7:30. You can call me on ***
