WORSE NETWORK COMPANY EVER

I tried to open up a Wi-Fi account with Telkom, to my surprise I had problems with them getting to my house installing the ADSL, I immediately called them an cancelled as if I was struggling with them to come out to my house for installation ,I'm definitely going to have problems in the future. Contacted the call centre cancelled it, agent gave me a reference number and emailed them ,they advised that its cancelled in a email as well. No router or sim received, no installation done, cancelled and got reference numbers. Now they sending me invoices almost like I'm a client of there's and demanding me to pay? FOR WHAT ?? You have done nothing for me and I have received nothing from you either. I have sent an email to query this and if they do not give me a proper answer or hand me over , I will take this further to the ombudsman. NEVER ,I REPEAT NEVER do business with Telkom. WORSE NETWORK EVER!!!!
