bad service, unhelpful

Our Huawei MediaPad was delivered on 9 September 2015, the night it was received we mistakenly inserted the sim card the wrong way and it got stuck. On the 16 September we phoned the number on the form that was delivered with the device which was the Mondo customer care line, the call operators were very unhelpful as I asked what solutions there were to this problem and they said they can't help me and that I must go to Telkom. We went all the way to Telkom Gateway as we were advised and the Telkom employee was very confused as to why we were bringing Mondo's product to them he said it is your company's product therefore your responsibility to fix it he phoned Mondo and once again the call operator-Kashmir if I'm not mistaken was very unhelpful and argued with the Telkom employee telling him that they must fix the device there. FinallyTelkom agreed that they would help us and send the device in to be opened up so the SIM card could be removed. Whilst registering the device to be taken in a problem came up. after having the device for a week the SIM had not yet been activated by Mondo so Telkom could not send it to be fixed!! Please advise as to what we can do ***
