Vox Telecommunications money thirsty without service delivery hrf

I signed a contract with vox in September 2023 and they accepted that monthly subscriptions will be paid on the 15th of every months. The first payment went through via EFT without a problem. 2nd month I received a link portal to complete so that payment can run on the 1st of every month. I send them an email explaining that I am getting my salary on the 15th as previously mentioned. To my surprise they suspended internet before the 15th. I paid on the 13th so that I can have internet to do my job. After payment, I stayed more than two weeks without connection. Fast forward they billed the amount of R3700 with threats that if I don't settle it will be handed over to the 3rd party. I request a cancelation and still have to pay R3700. For only three months with them in which I paid all my subscription fees without any use of internet. I'm liable to pay outstanding debts of R3700 and I am asking myself for what. 1st Vox has no customer service, no service delivery and don't care attitude which frustrate customers due to non communication when experiencing difficulties except chained emails with a ticket number has been opened but no one want to be accountable for assistance. Lastly I send them an email requesting a payment plan as I'm no longer working to avoid the consequences of that debt raised against me. They then send me terms & conditions that pertaining threads for me to sign which I refused. My advice to people is to avoid this money hungry monster at all cost because they will be liable to pay contract clause with no service delivery. Even when you seek intervention from ispa, there is no fairness against customers, they rule out to favor the isp
