Struggling to cancel LTE Contract

I have been tryung to cancel LTE contract (acc nr: ********** 06) just after orderung it on 22 March. Only after logging multiple disputes to cancel, I was adviced to fill in a cancelation form and email to the telkom cancelation department, which by the way the address does not exist anymore. Did that!! Followed up, kept on saying it takes 21 working days for cancelations. Meantime device was delivered, I wasn't there to sign for it so my domestic did. Phoned Telkom to inform them, the dispute was logged. Takes up to 7 days for someone to get back to me..... That also came and went... After multipile disputes logged after no feedback... Still waiting for someone to phone me to sort this nightmare out. I refuse to be held responsible for payment since I tried to cancle the contract within the cancelation period, because of a lack of assistance or NO service I can't seem to get this contract cancelled and device that's unopened and unused, to be picked up. Can someone from Telkom that actually care and now how, get in contact with me so that this problem can be dealt with. Your lack of service is unacceptable to say the least!!!!
