Penalised for being a customer with Vodacom for 23 years

I've been a client with Vodacom since 1999. Vodacom is penalising me for being a long term client by doing the following: 1. Higher subscription fees with cheaper phones, less data, less call minutes and longer contract terms 2. The call centre agents try to sell great packages but when it comes to confirming the deal they slip in that the extra data will cost extra money 3. The call centre agent's headset is on the desk and not on the head. So calls come in with auto answer and no-one speaks to me 4. Call centre agents cannot commit to calling me back 5. I have been trying to get assistance with an upgrade for the last 3 weeks no joy 6. I have one contract going onto pay as you go from 1 Aug 7. I will not pay penalty fees for the other two contracts (no handsets) as I am not getting service from Vodacom (see points above and below) 8. I logged an incident months ago about bad reception in my area - Ballito and no luck 9. My accounts were always paid 10. I have 8 contracts with you??? 11. I am going to litigate the matter 12. Get transferred from one department to the other department all the time
