Telkom incompetence

Oh Telkom, my dear Telkom. Even when leaving the country, I still have to deal with your incompetence! On the 2nd of April, i went in to my local Telkom store to give my 30 days notice. Meaning i wanted Telkom to close and end my contract effective 02/05/2019. But nope, not Telkom. You guys don't understand that concept. Since then my account was suspended 3 times and full out cancelled twice. Each time cost me an hour phonecall or a visit to my local Telkom to try and explain the situation. Finally, i decided to just leave it together and i let Telkom cancel my account all together until i leave SA. So i contacted Babalwa from my local store and told her to please just cancel my account all together because it was not working anyway, and she told me that she loaded a dispute. I also cancelled my debit orders as i gave my 30 days notice and all. I have ALL the emails by the way. Now, sitting in England, i just got an invoice for TWICE my monthly installment. WHAT THE F%&@#!!!!!!! This is absolutely rediculous. How can this company still exist with this type of incompetence!?!! Please, why can i not get this sorted? Please sodt this out for me once and for all so i can finally be done with Telkom. Thank you
