Supersonic's customer service is useless

I have tried tirelessly to get my FLTE working again without any success. Supersonic's whatsapp customer support is absolutely ridiculously pathetic, so I tried to go the call center route and was cut off after 40min waiting in line. We have online university exams to write within 36hrs, and cannot get the internet going after numerous frustrating attempts. After trying to get out of this subscription die to poor service since March, I have managed to get a termination date of end of June or July(received double communication). Can't wait to get rid of this incompetence.
