Bad service

My account was debited twice on the 01/12/2017.I immediately contacted Hollard and an agent first said that the debit did not go off in November therefore it went off twice in December.Your agents do not have the facts before making statements like these as the debit had indeed gone off my account for November as per my bank statement which I had sent through to Hollard on the same day.I received an automated response which said I should contact you within 2 days if I have not heard from you.(I do not see why I should be calling repeatedly whereas when Hollard is trying to sell you a policy they call you incessently)I called back today7/12/17 only for another agent Godfrey to tell me to call back on monday as he did not have any answers for me to which I then asked for a supervisor only for him to tell me that the supervisor os going to tell me the same thing.Godfrey then proceeded to put me on hold for more than 10 minutes on the supposition that the supervisor will be assisting me soon only to be told that he is busy and would return my call to which he still has not.Your call centre staff are rude and clueless and need training as they talk on top of customers instead of listening.I would like my money back please......
