Telkom fails to close account upon online and physical (in store) instruction

My unemployed pensioner of a mother in law (55) has been battling to get her Telkom account (***) (number: ***) closed for months now with no luck. She paid R2844.27 in the beginning of August 2020 and nothing was done, even after she approached the Telkom store (Liberty Midlands mall in pmb) requesting for the account to be closed. This was 2 months ago. My wife had to intervene and completed an online form on the 25th August 2020 and to date nothing has been done. My mother in law is now receiving statements of R100 per month, and if she doesn't pay, will be handed over to attorneys. To the greedy *******s in Telkom: please close this account or I will have you splattered all over social media !! I will not ask so nicely again.
