My 36 months contract with them ended. They are the ones who even called to remind me, and ask if they should cancel or if I still wanted to proceed with them. I clearly asked them to cancel. Next thing I know, they said I owe them 2 months instalments. How?? Fine, I paid! Guess what, these idiots still reflect on my Clear Score and have messed up my record! They are still sending me communication calling me their client. Honestly, when does it end??? Our contract ended. How am I still your client? Based on which contract??? Take me out of your system. *******.
