Supersonic worst lte provider ever be aware

I'm absolutely disguisted with supersonic there services are absolutely appalling I'm a new client and took a LTE bundle the price plan R249 now it's just me and my husband using it on our phones for Facebook and a game I have had to top up 2 times R150 each time that's R300 extra on the bundle of 250gigs they suppose to provide that should last a month on 2 phones no YouTube etc, ife logged 4 complaints already for them to call me as apparently I'm out of data again but I'm refusing to you up they are giving me missed calls my phone doesn't even start ringing it vibrates once nd 4 missed calls later and still no help do the employees not know how to make calls. I brought 6gigs on my in network and amazingly I still have data so u people are ******* I'm canceling with supersonic worst service ever I'd suggest them to nobody
