SOMEONE AT TELKOM PLEASE RESPOND - ANYONE!!!!!!!

I have TWO tablet contracts with Telkom. From November last year they have been sending me emails to say that i now qualify to upgrade. i tried for 2 mnths to get through to the call centre. its an unbelieveable struggle to get thru. when i finally got thru towards the end of December i was told i can only upgrade in March. Fine. i then started looking at packages that i wanted to take and found that what i wanted would not work in my area. i therefore struggled again via FB etc to get someone to help me with a cancellation form to cancel my contract. Finally i found: Richter Wahl (RB) ********** on FB and he promised he would be willing to help me with new contracts. i then explain after a week or so that i would rather just cancel my contracts as the service i recieve from telkom is POOR. He explained that i would have to cancel my contract a month before the time so on the 20/2/2018 i started my long process of cancelling my contracts. i faxed the docs to the number given i email to ********** - however my emails come back saying the inbox i full. so i tried ********** again and asked if he would please help me cancel. no response since: 20/2/2018. i got hold of someone else Rulani Constance Ndlovu (RC) ********** Who also promised to help me and i have also not had a response from her since. 25/2/2018+-. I have now given up. i dont know if my contracts are closed, as i still have people calling me to ask if i want to upgrade. when i ask them for help with the cancellation i get cut off. so what must i do to get someone from telkom to assist me. all i want is to either upgrade to something that will suit me or just cancel the contract s and i will go somewhere else to get help. there is not telkom in Theunissen so i cannot quickly run in an ask for help. SOMEBODY PLEASE HELP ME OUT OF MY CURRENT MESS!!!!!!!!
