poor service old mutual

having problems with Old Mutual - i asked a withdrawn on 20 June 2018 and the forms indicated it takes 15 working days. their customer care is non existing as everytime you phone you keep on holding for hours - when you send an enquiry to their website all you get out is "we are busy processing" this is the worst customer care ever from a big company i received. i would like Old Mutual to explain to me how they count 15 working days as we are now on 17 already and no money paid to me. i have a vehicle problem to get to work and this does not help at all in my travel to work. i expect Old mutual to react to this complaint
