My line got disconnected yet I paid.

I'm very disappointed in the way Vasco treats us as their customers, I've been on a 120GB LTE data package (Telkom) for the past 7 months and I've been debited on the last day of month every month. This month they did the same thing but to my surprise my line was disconnected last Friday, I attempted re-inserting my sim card again on Sat, Sun and Monday but it's still the same I had to purchase data from a Vodacom line which cost me around R200 in order to be connected during the easter holidays so I can surf through the net, do my assignments and stream on the tv which was of great inconvenience. I tried calling through to get a consultant to assist me, but it does not go through to anyone.

I need my line open ASAP!!!! My studies are dependent on this data; I hope my complaint will be attended.
