Pathetic Service

I had a contract with Telkom. All was going well until I upgraded to another phone. I had capped my contract since it was an open line and they didn't allow me to change to a top up contract. I couldn't understand why my installment came up to 2000 because I had capped it to not go more than 500. I called the call Centre and they logged a call but nothing was done no one got back to me. They debited my account I reversed it. I kept reversing it until they handed me over. I am fed up with Telkom I want nothing to do with this network. It is the first time I come across such in my life. Even the call Centre agents don't know what they doing. They make you hold for long but never resolve your query. Pathetic service I'm cool with Mtn and Cell c.
