Do not attempt "Change of Ownership"!

My other passed away recently (DSTV was in her name), I completed a Change of Ownership, incl new banking details on behalf of my Dad (82!), 2 days later, they cut off his service ("Sorry, we in error processed as Service Cancelled") Restore service. 2 days later, again cut off. Call Centre, Again pay (?!)(2 debit orders against my deceased mom's account were processed though, plus I have manually paid. Twice now from my Dad's account!). Restore. 3rd time, same. No jokes, this is now the fourth time, and I cannot escalate/ get hold of someone who can permanently resolve! For crying out loud: YOUR form, including all required documentation submitted to merely CHANGE OWNERSHIP! I merely want to ensure continuation of YOUR customer. You still can't get it right....?!
