Took 5 working days for my initial reply a couple of weeks ago and back and forth since has been 3-5 working days for each message. Currently 5 working days without a reply to my last message
I've given up frankly.
My order (£25) was also a low value order like yours and I'm just glad it's happened on an order like that and not a graphics card or something expensive I would be fuming!
The whole process is unprofessional, the first person to reply to my ticket had a footballer as their avatar. The second person had a some sort of cartoon character holding a gun! This stuff doesn't bother me just shows a lack of professionalism.
Best bit is I wrote an honest review of the product about it's poor quality and that's not gone on the website either so it's nice to know that reviews seemed to be cherry picked.
EDIT* i'll take the review bit back, just checked and it has gone on there.
I'll tag
@Doric to see if they can help you
