I am impressed with the easy ability to order asbestos protection equipment and that the website also suggests other items to consider, however one item on my order was incorrectly sent which did cause us a problem at the time of use. (ordered a double bag set and was only sent a single bag set)

Customer Comment:

Item was urgent requirement and guaranteed next day delivery - received three days later


On 30-Aug-2017 the supplier responded:
Firstly, let me apologise for the late delivery. This fell well below the high service standards we set ourselves, which I'm sure your Hatfield Peveral office would confirm. Unfortunately, the website link to our internal sales system had a technical issue, consequently we had not received the order. I understand Terry in our office explained this verbally once we were aware, and the items were despatched immediately for next day. Again,apologies if this caused any inconvenience. As Environtec hold an active sales account, please order in future via sales@safetyindustries.com thank you.
