Extremely Dissatisfied with delay of Re-imbursed funds

Case number ********** 0 I've been billed twice for the broadband package device which I returned within 3 working days of receipt thereof. Since 9.12.2017 I've been calling into the Telkom call centre and speaking to people like Thandeka of Billing dept / Afkin Langeveldt who confirmed telphonically that the package was cancelled and that there would be no need to confirm this via writing nor a completion of a cancellation form was needed / Phulile / Ntabo on 13.12.2017 took my call and promised to have the team-leader Audricia of Durban office to run with complaint- To date no call has been received/ *****gwa on 13.12.2017 received my cancellation completed form and promised to sort out. I just spoke to Modise who promised to email Bianco Dela whom I have 3 times emailed and NO response. Meanwhile I have received another bill from telkom billing me for this product which they already have in their possession. I ambeyond irate with Telkom for their disgusting service
