Pathetic service from a bunch of clowns !!!

I'm probably wasting my time posting this, as Telkom don't respond. I'm still trying to cancel my Prime video subscription, have been for the last three months, but going round in circles with their pathetic service. Today, unbelievably, the jokers sent me a Prime video offer to subscribe. I can access their app & website, but get stalled at every attempt to cancel the subscription. They are *****ing my money !!!!!!!!!!
