bad service

21st of May I cancelled my investments policies with old mutual ,I receive sms week after I cancelled that residential address is missing, I scan and email residential address the again, week after the debit order went through ,went to them and ask what is happening they told me because residential address has been not received, I ask them how long will it take for me to get my money back, for the investments and debit order that went through they told me 15 working days ,so I'm suppose to wait 15 working days plus 3 weeks that I waited before I get my money , I'm not happy with old mutual services
