ADSL contract not cancelled

I gave notice of cancellation of my ADSL contract online on 04/05/2018 for 01/06/2018(Ref nrs ********** 8, ********** 6, ********** 4) because I moved to a complex without Telkom ADSL coverage. I received a call from Lerato Makhele , Fixed Line Retentions on 23/05/2018 to confirm cancellation and that there will be no penalties due to no coverage in my area. The case numbers relating to the cancellation show all as "Resolved" but infact it is not resolved. My ADSL could not be moved due to no coverage in the new complex I moved to on 01/06/2018. Needless to say, I'm still being billed and the contract was not cancelled. I have e-mailed my new rental contract to Lerato as proof of my new address but haven't received any confirmation from her. So currently I am without internet but are being billed for it. FIX this ASAP Telkom!
