Bad service

good day i have been signing in to their online betting, i have submitted two times proof of address and my ID but still there was no response and then i email them first time they told me that my proof of address have no stamp from the bank, and my ID is cut, i sent them the correct one the full picture of my ID and my proof of address with a stamp still they told me that they don't accept the proof of address the changing of bank and scanned documents, what i am asking what do they want really is it the proof of address and my ID document or something that I don't know which they do know about I'm getting tired with their demand which is are lame and not making a sense why did they create something that they cant service i have been sending my ID and proof of address like that have never have problem at all with other companies except them.

Thanking you. Khanyisile
