waiting 24 YEARS for a query to be sorted

Is it reasonable to wait 24 years before you give up. I have waited 24 years for Edgars to update my ID number to reflect the last three digits of my ID number. They still have not done this and insisit on sending me statements where their system wants me to put my old ID (FROM 24 YEARS AGO) into the system so that I can open my statement. Its so long ago that I have no documentation to show what my old ID no. was. So if I cant open my statement, then I dont know how much I owe, so Im just not paying until its sorted out. Have phoned so many people over the years that I now give up. It wasn't a problem really until they started sending encypted statements by email that need an ID no, to open the statement. I don't care if they hand me over for non-payment. I don't need a credit score. I don't care if the black list me. I JUST DON'T CARE ANYMORE!!!! My name is Melody Edwards and I live in Pretoria. When you sort it out, I will pay. No wonder you nearly went bankrupt. Its from employing idiots on the floor and idiots in the call centre. In fact, I've had an account for so long, it wont even take my account no in the system when I call. So I JUST GIVE UP!!
