What a ******* service

I would like to complain about the shoddy customer service I have had with Hollard. I started receiving marketing & spam SMSs from them and had to complain to get these to stop. I did not opt in to any use of my contact information for SPAM. As a first point of contact regarding my policy I then received an email with no branding or information on it - it was just an attachment with my name incorrect and 'Please find your correspondence attached. Regards, IUA Business Solutions'.I have no idea who 'IUA Business Solutions' is. I have no relationship with this entity. There was no cover letter, just the policy. My name was incorrect. My address was incorrect. The year of the car was blank on the policy. It took 6 days to receive a reply. I was told in the next email that the incorrect letter was sent regarding the Policy. They still had my address incorrect. I complained again & I then receive another email stating 'Please find attached updated policy schedule with the correct address.'However I had to email back yet again as the address was still wrong! I have had to send so many emails and deal with such poor customer service - I do not want this company to engage me again.
