worsed service

For more than 3 years I have been struggling with ABSA home loans to email my statements to me. I have gone into the bank twice, I work overseas and this is the only way I can receive my statements. Once they got it right and emailed my statements, the next month I received an email of someone else's statement and never received mine again. They are very quick to phone and harras you when you have not paid them but not capable of emailing you a statement so you are aware of what you are to pay! Being a bank, how difficult is it to do this calculation? I have even reminded them that the law demands I receive my statements but for some or other reason, more than 3 years later they still can't get it right!
