Poor Internet service & *********** staff

I have had an awful experience. I used to have rain as my service provider as there is no fibre in my area. I then switched to Vodacom to house all my products to one company. What a huge mistake whereas Rain is month to month I entered into a 3 year contract which is fine however I cannot get NAT type 2 so what that means is that I have firewalls blocking me communicating with my friends. I went to the branch at the Grove, they couldn't help me, I then went to the branch at Menlyn, I wasn't assisted & I was told to go to Vodaworld. I drove till there and they said I should fill in an unrestricted APN form which happened in April of this year. I then submitted all the paperwork ,(form plus ID copy). I received an sms that it was completed but when I tested nothing worked. I called customer care asking can't they send a technician to log into my router and change the settings, they asked if I can submit the forms (unrestricted APN) which they have on their system. that was after I was asked to reboot my router after 30 seconds, what good was that going to do?. this initial call took place in May. In June I followed up and I had to go through the exact same thing, towards mid June I had enough and enquired about cancellation as I am not receiving the service I require despite me paying them R1000 a month for poor internet capability. They wanted me to pay R24000 to end the contract. Imagine paying them R24000 but not givng me the data? anyway so now what am I to do when all I want is for a technician to come and sort out my router and if they cannot provide what I need why am I to be held liable as this was not was sold to me. I then attempted one last time to call them (mind you at no point am I ever informed of things if what I am asking is being processed or the progress thereof) then after being on the phone for over 90 minutes I was told they have done everything on their side I should go to a branch and take my router and activate "it" from there. So like a fool I go to Vodacom and they ask me what am I talking about? I left another company (Rain) to bring my business to them only to be disappointed and I have other contracts with them. as a customer I pay almost R3000 a month to them, surely I deserve better service than this. so now to get what I want I am forced to go to Rain pay them for a service that I actually want and simultaneously pay Vodacom R1000 for internet as well. thank you so much for this amazing service Vodacom.
