poor service -money laundering

I started a funeral cover on the 26-09-2019 and instructed First National bank that the debit order should go of on the last day of the month. Which they did for the 1st 2 years then they starting messing me where there will not not debit and double debit the next month which was is total inconvenience. In November 2019 the same thing happened where there was no debit and in December they double debited me I had to reverse one debit order, with an agend knowing that in January 2020 they will still double debited. I had funds in my account till the 10 th of Feb but to my surprise I receive an sms that 3rd of Feb that my policy has lapsed. I sent an e-mail to *** enquiring about this but they said due to cancelled debit order. i wrote again asking them what about the inconvience of them double debiting and not debiting and requested for the policy to be reinstated without me waiting for the 6 months period or returns my premiums but I have not received any communication. The most annoying thing that when they dont debit they dont even send an sms to apologise. I will be taking thsi matter with my legal team. To think I have recommended them to other people. Totally disappointed.
