Dishonest call centre agent

I received a call from a lady by the name of Alicia from Africa Credit Solution at around 08:30 on 21 September 2015. The lady offered a voucher offering and she was busy confirming my banking details. Before I can even indicate whether I am interested in their offer or not she dropped the telephone. I suspect that she will indicate to her superiors that I took that offer and that is not the case. I called all the numbers that appears on Africa Credit Solution website and to my surprise people who picked up my calls said they do not know Africa Credit Solutions. Fact is I'm not interested in doing any business with this company and I want them to remove all my personal information from their system.
