Angry TELKOM customer

Telkom and it's ****py billing! I cancelled a contract in August already! I understand the 60 days notice which gave you September & October 2020 to bill me, and you did. Why bill me in November? I WANT MY MONEY BACK! I had to take time off my busy schedule to go in store so I could get through a consultant because their customer service line didn't go through! 2 weeks later I am still waiting for my refund! I don't know why I keep doing this to myself where I could actually switch over to a different ISP...
