Useless telkom service

So fed up with telkom. They debit R1815.14 from my account on the 2 May 2020. They send me an invoice after that of R3800. When i call them.i stay on line waiting for 30min without any consultant helping me. They have the wrong physical adress on my invoices and i have phoned 3 times about it still not fix They put my line off so i haven't use any of my internet for a month and i have paid twice already. In 1 month with out any service. I do need a response from them today(4 may 2020) Other wise i do nee to take future actions.
