I sent the eBay seller a message last night and, to be honest, have been pretty disappointed with their attitude.
I sent the message at around 9:30pm. Asking when they will have more in stock. He/she responded at about 11:50pm by saying that they were due back in at the end of February. I then asked if they could reserve me a pair, to which they replied "not now, you've already woken me up" - I apologised and said I would contact them in the morning.
So, I replied again, at around lunch time and they then proceeded to tell me they didn't have the setup to reserve anything...to which I responded by asking them to take note of my number and if they could call me then, when they are back in stock. Had no response after that.
These might be a great buy, but the sellers attitude is putting me off from doing any business with them.
