Pathetic Customer Service, Very Disapointed

My customer I ordered a Rain LTE sim card from Rain on the 23 July 2019 and received package on the 25 July 2019 and my service was also activated that day. You then get 7 days free unlimited internet access which started on the 25th as well. My problem with service is that I selected the "R250 Unlimited 19 Hours per day Package" which I thought is just that. Now I am not a tech savvy guy but to my understanding is that I will have the unlimited internet and from 6pm till 11am I will not have any internet access as this is the plan I selected. To my surprise I logged in to my account and saw my Bill was at around R1700. I then contacted their support via Live chat on the 8th August and after I entered my query then the chat kicks me off. I did the exact same on the 9th August as well and the exact same thing happen and just got email saying " an agent will contact you back" which never happened. I tried the chat feature again on the 11 August again and it kick me off chat again.

Eventually I called the call center on the 11August and held on for about 30min and spent talking to an agent who does not know what she is even doing there. She put me on hold for long periods of time trying to find out what I am talking about. I then requested that her Manger call me back who she referred to as a George Bida (it sounded like she said Bida) and she did this with attitude as well. This so called Manager never once contacted me regarding my query

What I am getting at is that my bill is standing at over R2000 when I selected the R250 plan. How many non tech savvy people are this company robbing like this? Their Customer Service is pathetic. I need someone to contact me from Rain asap on my cell as I am not paying anything more than the pro rata amount and the one month upfront. I selected a plan where the internet is not available from 6pm till 11pm and that is the only thing I am going to pay for.
