STRUGGLING to cancel my account!

I can not access my billing information online or do my online cancellation. As soon as I want to upload the required documents for cancellation, the site throws me off. I have also tried talking to a consultant online, but after 30 seconds of sending my message, it also throws me off. I have sent relevant documents via email to correct email address for cancellation 31/05/2020 as I would like my Telkom lines to be cancelled with immediate effect.

This is not the first time I am struggling to cancel my contract.
