Disgraceful service

I have had a billing query from June 2025 i have called and logged cases however i have had no assistance no calls i have queried why i am receiving invoices with zero billing and everyone that i asked for help told me dont worry if your invoice is zero you owe nothing i have sent the invoices to query why my billing is zero and now after 4 months i get an sms to pay R1340 and if i don't pay then will charge me another R202.70, i do not understand why someone competent cant deal with my query and give proper feedback why is the customer service where is the apology for invoicing error why is there compassion to say yes it is our error can we help you do a payment plan, I have gotten such good service from openview but Telkom is just pathetic. i know so many friends and family going through the same billing issues i recommend people cancel and go with another service provider and i plan to do
