Not treating client fairly

I spoke to Sershen on the 2.07.2015, I was adding the vehicle on the cover and requested the start date of the vehicle to be 25.07.2015 as we still covered by the other insurer.He sent policy schedule with wrong details, I called the office to rectify the mistake and I was told the vehicle cover started on the 2nd July already.I have been debited the pro-rata before the commencement date of the policy. Im sick and tired of momentum *********** staff. I WANT THIS TO BE SORTED ASAP OR I WILL MOVE MY BUSINESS TO SOMEONE WHO CARE FOR THEIR CLIENTS.!!!! <div><br></div><div><em>(Supplier name changed from Momentum to Momentum Short-Term Insurance by Hellopeter.com)</em></div>
