Shocking service!!!!

All I want is a new invoice for this month with the correct billing amount.! My debit order went through the second time it was debited and now I have been billed double? Due to the pandemic I am really struggling to make ends meet and cannot afford a double bill! I have sent through more than 10 emails, sms's, chatted to agents on Facebook sent through my proof of payment over & over. And yet I still get annoying automated phone calls harrasing me saying I have not paid when I have paid and sent through multiple proof of payments. I even went into the Telkom shop at Eikestad mall wich was a total waste of my time as they can't even assist with billing department enquiries. I even said I'm going in on FB chat and no one responded to tell me they can't help. Your service is shocking. Can't wait until my contract is finished so I do not have to deal with this stress and frustration. I do not need this problem in my life that is Telkom. 9/10 calls drop! My mom even knows its me calling because she can only hear herself echoing back to her.
