Unable to CANCEL Telkom Wifi and Fixed Line !!!!!

I am tired and fed up of Telkom's terrible service! After waiting since the 30th of May 2018 for my services to be relocated I have decided to opt for a better internet service provider with better customer service. I have been trying to cancel my fixed line and wifi services but the online registration process sucks! It asks for an OTP which is only valid for 3mins....but the OTP is only sent to my email after 15mins. Then if you try use the OTP it asks you to resend for another OTP! The cycle keeps going on and on. JUST CANCEL MY SERVICES I AM FED UP!!!!!!!
