Appalling service

Appalling service from Telkom. Am so fed up I want to cancel my contract. Treating your customers like ****. How many ****in times does one have to call you and talk to your ****in agents to get things done. Been asking for my tax invoice since August. Spoke to Sisi 2 weeks ago and again Cindy today and they both promised to send the tax invoices for August and September but still nothing!!! I want my ****in invoices now ****it
