Zero Customer Service=Old Mutual Call centre

So this company has been debiting my account each on on the 24th instaed of the 25th. It is such a mission to get through to the useless call centre. I have been trying to make contact with them for the last week with no luck of reaching them( now imagine how much time I have wasted).

I have 2 policies with them and they are debiting on different days( how so?) One on the 27th( which is fine and the other on the 24th( Now this one is messing my credit score as I have not agreed to this date). Now please also make it for the 27th or cancel both policies

I have so Fed up with this company...Lets see if they can sort out this mess that have created
