Received an email three weeks ago informing me my subscription order was due to be delivered. I waited and waited, no delivery. Emailed and received a reply, with an apology as a digital error had occured, which they were looking into. The order was sent first class mail, which I received today. Pleased with the service from the Support Team.

My current subscription had been cancelled due to a transfer issue to the new system and as an apology I was given a 50% discount on my re subscription which was a kind gesture. Optibac has really helped me out and it’s a great product.
