Disappointed customer.

Firstly I waited almost 3 months to get documents for my policy when I first signed up. Second incident, I clearly asked that my direct debit should come out on the 28th of every month, nothing sorted everything kept and left as is, it was changed eventually. Here is where the issue lies. It was on the 30 of April 2021 I checked my bank, no payments taken. I immediately contacted the agent that signed me and and she suggested that I make a direct payment using the account details she provided. Later that night I got debited from Old mutual making a definite double payment. They checked through everything and I even sent proof with my bank details and just for them to turn around and say they got nothing. 3 months almost and not a single thing resolved. I'm really disappointed with Old mutual I had nothing but stress with this company.
