我们预定明天从阿尔戈斯运来一个新炊具，将由他们连接起来。我需要在我的新炊具到达之前(明天早上7点到下午6点之间)断开我的旧炊具，但我遇到了一个问题。The screw that holds the blue wire into the socket has snapped on one side so the screwdriver cant grip to turn the screw to release the wire Is there anything i can do or am i going have to call an electricial to come fix it? Which would mean me having to also pay for someone else to fit my new cooker as dont think i can change delivery to another day now. Thankyou
