Ignored my account cancellation

<p>Good day<br /><br />I sent in the documentation to cancel my mother's account with Telkom, but not the line, on the 19th of September. I received an automated message saying that an employee will contact me within 21 business days. Being busy with other matters such as university, I completely forgot about it until my mother let me know that she was still being charged for the account. She has now been charged 3 times after I sent in the cancellation form, and still no one from Telkom has been in contact with me. Surely she at least deserves a refund for at least 2 of those months now. <br /><br />Regards</p>
