Worst experience ever!!

I have had such bad experience and customer service from Supersonic, for the past week I have had issues with my data, I have a 60gig subscription, 30day and 30 night (once you run out of data the router goes off line and you need to do a top up) but instead for some reason between 4:00 to 6:00 in the morning I used 55gig and went over with 29gig (I am told there could be a glitch in the system, this is why it happened) not one device in my house was connected at that time and no one can explain to me why it went over the 30gig, I did the top up of 50gig which was suppose to cancel out the 29gig that went over, this was never done so now again my router went off line since Friday the 12th and they keep in telling me my night data is in minus and I need to do a top up which by the way I did on the 4th of Feb already ( so why must I keep on paying for data but they can't update this on their side) worsf part is the tech department keeps in telling you it is not something they can help with I must speak to customer service, well surprise surprise there is no service, since last week I have been fighting and waiting for different supervisors to contact me (a week later and still nothing) worst experience ever, I have never had such bad customer service with anything in my life, I am done, I have put in my cancelation request, actually hoping that this will be processed correctly (as I heard people complaing about this as well, they cancel their subscription but after the 30days, supersonic still bills them) I will not recommend supersonic to anyone, I could not care less about the good prices etc. I can't deal with bad customer service, honestly can't wait for my subscription to end because what's the use of having a subscription but no customer service. I actually start laughing if I'm told someone will contact me, because it never happens.
