Incorrect premiums being deducted

Really disappointed with Regent / Hollards service

My dad has an insurance with them. 2019 or early 2020 they failed to deduct the debit order. Apparently a system error. We had to call them to rectify the mistake they didn't even pick it up November 2020 they double deducted and now again in January 2021.

And it's again a call that has to be made at our expense to fix it.
