address

after my last entry on hello peter I received a cheque account bank statement 13/3/2015 with my correct address. this month however I received a cheque account statement dated 13/4/2015 with an incorrect address on once again. I fail to understand how a statement can be send one month with the correct address and the next month it has a different address on. not to mention that i receive two other statements from Standard bank with the correct address on, but only my cheque account statement has the incorrect address. how can the same institution send 3 bank statements, all with different addresses on? Is it so difficult to make sure all the addresses on all my statements are the same and correct. I spend over a hour in the bank with my fica documents to make sure the address got updated correctly on all my profiles.
