An update.
I got through to them on the telephone, the lady said that she would call the warehouse to see if they have the item in stock. I asked her to call me back once she had done this. She then did it whilst i was on the phone. The number for the warehouse was engaged so she said she would email and then get back to me.
I then got a phonecall back from a previous online message i sent across, they tried to reply a while after i had sent the message but i had the window minimised. I believe the chap was called Nick, he said there has been a mix up and the supplier had sent the wrong headset to them (helicopter connections) they had managed to source another one and they are shipping it next day Saturday delivery !
A bad situation nicely resolved ! Its a shame i had to jump up and down for it but I will give them their dues !
So long as it arrives tomorrow as promised i wont have an issue using them again but i may be paying for next day delivery in future !
Thanks for you help !
