Pathetic service from Telkom

On the 31st of January 2021 I've requested telkom to cancel my service once my contract expires/ends on 22nd March 2021 and move my number to prepaid. I specifically stated the service should end 23.03.2021 and I received an email informing me someone would contact me in 2 to 7 days. Yesterday (01.02.2021) I found out they went ahead and cancel my number without contacting me first and now I'm sitting without a phone number with no airtime and data and they expect me to still pay my bill for February when I don't have any airtime / minutes or data. I need someone to contact me urgently and reinstate my phone number and resolve this matter urgently! Alternative number to contact me is ***.
