Flash business hidden information before opening account

They mislead people by not giving the whole information before you can accept to download their app, because they don't required any documents to be send to them to activate your account before you can use it but after topup they will close account and need bank statement if you have used bank to top up, id copy and proof of adress, is misleading information because they should have let clients to know that before doing any payments in case you need to use electricity or airtime as emergency. If the balance shows on my account that i have paid so much why they need proof of payment because they have to request that if the amount is not shows on my account. Clients must be told in blank and white on what requirements they want but to hold their money after you have benefited to them.
