Good afternoon Robert,
Thank you for taking the time to leave feedback.
I am sorry to hear that the impeller developed a fault, please accept our apologies.
I cannot see that you have ever contacted us about this issue to allow us the opportunity to resolve it for you.
I have arranged for a replacement impeller to be dispatched tomorrow; it should be with you on Wednesday 18th September.
Apologies for any inconvenience caused by this faulty part.
Best wishes,
Laurie
