Worst internet service provider

They created a new order when my account is already active I just wanted to renew my internet voucher but their customer service agent named Craig decided to create a new order which would me I am not able to have internet and I work from home which means it affects my income and causes me to be called into a disciplinary meeting due to my lack of attendance for 3 days and when I call their customer service and ask for their supervisor or escalation team they drop the call on me and one agent even told me to call vumatel because it’s not their fault and I told her I cannot call a company I did not pay I paid them they have the worst customer service and they do not live up to timeframes given and false promises through texts they send
