Billing issues with no SLA

So after 4 months and 7 days of being sent from pillar to post I'm now force to post this on Hello Peter as the current channels I'm using ***, Deanno, Denzil, Tebogo and the hundreds and agents I've spoken too. No one can help me to get my issues resolved, I or let me say them (Vodacom) has been waiting for 3 months to get my call recordings<br> <br> So in May I order a 5GB sim only contract to use with my WIFI router. Our thinking If we run out of data I'll simply purchase a pre-paid voucher and off we go.So around 6 June I noticed that the router stop working. I decide to call the Vodacom to understand what's happening. So they tell me I've reached my limit and I'm like okay I'll just purchase a pre-paid voucher and they tell me no. I've reached my bill limit with was R9800 and some change. So naturally I fall of my chair and dispute this madness. So I'm trying to understand why I am running a bill if it's pre-paid. So continue to explain to me that this is an open line. So Vodacom explains to me that when an agent calls to confirm an online order they need to make sure that the customer order the correct product as whether its an open line. PLEASE HELP ME TO RESOLVE THIS ONGOING I
