Bad bad bad dont ever attempt taking on a contract

I need someone from Telkom heaeoffice to contact me urgently. What pathetic service trting to purchase a device online with multiple failed attempts. After finaly receiving a device it is faulty with a software error. The phone switches off randomly from the very minute it has been switched on. We contacted Wendy Baloyi the OPS Specialist who has been assisted us, who promised to have the couriers collect the device the next day. Currently its a week later and still no pick up. After trying to contact her on numerous occations she finaly sends us a mail where she communicates with Shielah Maluleka but unfortunately from there still no response or futher communication has been receives. We phoned the call center who advised us to go tto the nearest store but to no surprise the storw refused to accept the faulty device only once again logging another online request which we probably also wont get a solution from. All thats happening is we are being sent from point A point B only to be sent back to point A again. Is thia how Telkom deals with queries or is this a way to delay the cooling of period so that thwy can turn around and say you have no foot to stand on because you are out of the cooling off period??? We dont want a faulty device infact now we dont want to deal with Telkom any longer. We want this contract cancelled asap. Please someone reliable and competent respond!
