Bad Service to assist in payment

So Telkom handed us over to you guys. We cancelled in May 2017 with them and they processed the cancellation in September 2017 and we are being held liable for those months of debits. This is unfair and we will not pay those months and you guys don't even see that it's against their 30 day cancellation clause. I have requested seperate invoices numerously from December 2016 from you guys for the spesific months we owe as we would like to pay. But we will not pay from end June as that is not our responsibility due to telkoms lack on admin s****s. Please get back to us with correct info following the customer protection law as we are not saying we wont pay we will just not pay those months after 30 days since we sent our cancellation to them. I have emails as proof and Mokgadi was not helpful at all.
