I have move from another platform to Magento. I import the old customers data with CSV into magento.
There is some error after import. The date in 'customer since' column is wrong. It shows -1 for the year. Besides that, some is showing the future date, eg. 1 of Dec 2013.
When the customer log in form frontend, sometimes they see different name. They see other customers name from different customer group. The price they see also will change.
I would like to solve this issue.
