Transunion must deregister and disappear because of nondelivery

How many times must I call in a month to activate a simple monthly subscription? Today it is the sarcastic Caroline at the call centre who find it difficult, or impossible to assist. Can anyone suggest a better, more reliable credit bureau that I can use for the rest of my life? In November and December I tried to have them update my profile and correct an error but it was never done, all I need is to verify if it was done after 2 months but I can't even check. They must rather deregister and disappear.
