I'm still paying for services cancelled!

I cancelled my tablet and ADSL (after upgrading to Fibre) on the 3rd of Feb and I am still getting billed for these services! Now I hear my line has been suspended because my account is overdue after a Telkom consultant told me to ignore the invoice with the ADSL and only pay for the Fibre. Also, R99 is still being debited from my account for the tablet/mobile data contract which ended already (plus I cancelled it). They said I will be credited the amount and I still haven't received any feedback. I AM SICK OF PHONING TELKOM AND NOT GETTING ANY RESULTS! CAN ANYONE JUST HELP ME?!
