Problem with verification details causing big frustration and zero support when we needed it

I phoned MWEB on *** on Tuesday the 28th December. I needed to follow up on a call from the previous day as our internet line was down. However I had the most frustrating experience with the person on the other side of the line. They confirmed my phone nr I was calling from was correct, and then I was asked my name and my ID. Apparently something was incorrect with my answers. He can't tell me what, so he just could not help me. I will have to go without internet as my name and ID are incorrect!!! So he sends me a mail with update information for my account. Its four Pages and I must now go find all my latest accounts and business information and letters to prove who is the registered person?? I don't have time for this and feel this is grossly unfair. I am happy to 'update' what they have, but it does not work like that, I must complete all the forms as if I am a new customer. This is were my issue is, I have been an Mweb customer for YEARS, since they bought over Iafrica, (hense my email address ***) I have phoned them countless times and received great service. I feel my treatment was unacceptable, I am not going to complete ALL these forms like a new customer, I am happy to correct whatever incorrect information they have, although NOTHING has changed since we have been with them, so this whole exercise is so POINTLESS! So Mweb, I now have a dellema, do I complete all your forms, seeing as you don't know me anymore or complete the same forms by someone else, which sounds more logical. Please help?
