The retailer cited problems with a supplier that left many intended gift recipients empty-handed on Mother’s Day and prompted angry customers to take to the airwaves and vent on Twitter and Moonpig’s Facebook page.

In a statement released late on Sunday the company said: "We can confirm that an issue with one of our suppliers has delayed the delivery of flowers to some of our customers this weekend.

"We know how important Mother’s Day is and we have apologised to and compensated all customers who have experienced a delay. We’ve been working hard to put things right and by the end of Mother’s Day almost all orders have been delivered. We hope our customers accept our sincere apologies."

It isn’t the fist time that Moonpig has been forced to apologise: in 2013 the company published a full apology on its Facebook page after Valentine’s Day orders were mixed up resulting in cards being matched with the wrong gifts.
