They shouldn't be buying the deletion of opinions and discussions about them... They could simply ask that you posted up the finishing details and how they responded towards the end...
Instead they want the unbeknown's to not know anything at all and fall into the same trap... Hoping they don't get caught again . Keep the discussions, even if the problem is resolved, however if it is resolved, then that should be posted in the thread to finalize it for peoples references in the future.
Personally, the actions of Springwood marine has not shown me any hint of loyalty to their customers, and if I'm spending a heap of money, I expect service and honesty.
To the owner of AUSFISH, don't delete this stand up for your community and keep the discussions fair, allowing the retailer to defend themselves to the customer, and potential customers of the future.
