Poor service AGAIN and AGAIN

There was an amount of R470 that went off my husband's account on the 30th of April 2016. We don't know what this amount was for, so we called ABSA on the 30th of April 2016. We spoke to Jabilani from ABSA's call centre, he said that he can't find information on what the amount was for, but he will call us back in 48 hours. We didn't receive a call as yet. So, we emailed our so called private banker, Lettie Mokoena on the 4th of May 2016 and again on the 5th of May, but still no response. So what must we do to get joy from ABSA, the answer is to post on Hellopeter, because this is the only way for us to get ANY response in the past from ABSA. Will ABSA please contact us and tell us what the amount of R470 with reference NAEDO was for, that went of my husbands account?
