Worst Fixed LTE provider!

Supersonic has the WORST customer service I have ever come across! You cannot get in touch with them via email, phone call, or Whatsapp. They say they will contact you but never do! I have been waiting for a call since mid-April. At the beginning of April I spoke to three different Supersonic consultants and each of them gave me a different excuse or lie as to what was wrong with my data usage. They claimed that I was in arrears with my CAPPED account so when I topped up my account, they STOLE my money for the arrears. A capped account can not go into arrears. Secondly, I have installed programs on all of my devices I connect to my wifi to check my daily data usage. What supersonic claims I use each day, is not what I actually use. They cannot tell me where my data is going and why I am suddenly using so much that I go into arrears. This is just ridiculous! Where they claimed I used 4GIG a day, I barely used 1 GIG. They are *****ing Datta, *****ing money, and then refuse to contact their clients to sort out their problems. I will never recommend anyone to Supersonic and will make sure that everyone knows about the terrible service they deliver! I am appalled.
