Useless customer service from Supersonic, the next TELKOM !!!!

I have never seen such bad service since dealing with Telkom. I have requested for my Fiber line to be cancelled at the end of March 2020 and up until today 2020/9/23 my fiber line hasn't been cancelled after numurouse emails to Supersonic and sending Whatsapp message to the support number that you suppose to use on their website. I must be honest, at this point of time Supersonic is just as useless as Telkom when it comes to customer service. You never get hold of someone on the phone, they take days to respond to your emails and it seems that there is people working there that has no clue what they are doing cause they can't even do a simple cancelation and keep on sending you bills and emails to tell you your account is in the rears. I AM TELLING YOU GUYS NOW, IF I GET A BAD CREDIT RATING DUE TO PEOPLE AT YOUR COMPANY THAT DOESN'T DO THEIR JOB. I WILL HAND THIS OVER TO MY LAWYERS TO TAKE THIS FURTHER , AND THAT IS A ****ING PROMISS !!!!! SORT YOUR **** OUT AND CANCEL MY ****ING LINE !!!!!
