My initial contact with 'the shed' was around 11am and an initial response arrived 14.37.
...show 1784 in stock across our stores. A stock check and inspection has been requested...
Todays response started with over 1000 words about their responsibilities and liabilities. At no point did I give them the original purchasers name, these excerpts started way down the email:
...Thank you for bringing this potentially lethal problem to our attention. We trust Mr Collins is suffering no after effects...
...an inspection of the returned packaging reveals it has been resealed, our belief is the item had been purchased and opened then repackaged and returned to us for a refund...
Then words explaining the difficulty of inspecting returned items which appear to be in original condition. At that point I assumed they were simply going to sweep it aside and blame an outside party.
...we have done a stores wide stock check and inspection of 1738 of this product and not identified any occurrences of the issue you have raised...
...additionally we have identified another four products in our range which follow some basic similarities...
...a stores wide stock check and inspection of these 3164 items identified an error in one instance, this item has been returned to the supplier...
...we are in negotiation with the suppliers of all five products to ensure...
If we can be of any further help in this matter please do not hesitate... So I didn't hesitate and rang the phone number which surprisingly took me straight to Jeremy Henderson, being the signatory on the email. I asked about the discrepancy between the number of items checked and the original quantity quoted, apparently they get used 'in store' and written off and some get stolen.
They obviously took this seriously, big up to a shed.
