Pathetic service

All I can say: "Pathetic service" I've cancelled my landline 17 March 2020. I've received confirmation, after numerous email, that my line has been cancelled. They have also let me know that I have a credit and that they will pay me back as soon as they received my bank details and ID number. From confirmation up until today, I have received no payment. Every time someone new answers my emails and demand my ID and Bank details. How many times do you want me to send my information????? VERY QUICK TO TAKE YOUR MONEY AT THE END OF EACH MONTH, BUT THEY ARE VERY SLOW IN PAYING YOU BACK THE MONEY THEY OWN YOU!!!!!!! It's now another month, and NO RESPONSE!!!! Pathetic!!!!!! My next step will be to contact my lawyers. STAY AWAY FORM DOING BUSINESS WITH TELKOM!!!
