Bad Service

I have had a WiFi contract with Telkom through Mondo for over two years and have never had to enter a password when wanting to contact, all of a sudden I am being asked to do so...I contacted Telkom Direct on 29 September and spoke to Clarence Mondisa...who couldn't have been more unhelpful and rude if he had tried...speaking to me as though I was completely uneducated and plain stupid...without actually assisting me at all...I am paying for a contract that I cannot access or use...!
