sick and tired of this ISP

I wish I could give this ISP a half a star I have been having issues with my network speeds for more that a month now, I had a case logged on the 23rd and I queried it today and apparently it was resolved but my speeds are still as bad as before - this was the message I got on Facebook messenger- "Yell'o Naveer ॐ Singh, case was marked as resolved and a message stating that the speeds are best effort."

This is really ridiculous and for the past few month I have been have endless issues with this ISP

You guys have been *****ing customers over and over - paying soooo much for such a **** and pathetic service - but you'll cashing in and we- THE CUSTOMER - is getting *****ed

I have been given Supersonic chance after chance but I have come now to a point - I am going to cancel my service - atleast I will save on R998 every month and I won't have to deal with a useless customer service that can't even give proper updates or get the issue resolved!
