Telkom...the worst you can get

I am really disappointed as for years Telkoms service and customer experience is so poor. They always debit you way over your arranged contract agreements and you can never get your refunds.They are the biggest monopoly for personal and business communication yet the service is so poor. I renewed my contract last year for my FIber and I was given a 3 month free Prime video viewing. My family and I enjoyed the viewing so I decided to keep the it with the contract which is about R79.00 Four the month of April was debited for the Prime video and my Telkom bill which is way more than the normally agreement.Here we go again with the deceit of going against the arranged amount and to top it all they unsubribed to me the Prime video. I spoke about 6 different agents from the Telkom Call Centre and nobody can help They offer the Prime bur don't know anything else. The consultant advised I am subscribed but they don't know why Amazon Prime is saying this . Now I must leave my work and .take a trip to tbr sort ,billing department to assist with the Amazon Prims issue and for the debit order being incorrect. This is shocking. I am so fed up with Telkom. Great products but poor service. I need urgent assistance and nobody can assist.
