Watch only work till en of warranty expires. After service is bad bad bad

Good day. I feel a bit annoyed. I have bought a Huawei watch, to work with my huawei phone. I like doing sport and use my watch and phone to track my progress. I don't swim, sleep or bath with my watch. And I let it flat before i charges the battery. So I take good care of my watch. The warranty of the watch was in July. I was running with the watch when it suddenly started to vibrant. It did that until the battery died. It charged and did not want to switch on. Now it doesn't want to charge anymore. I toke it in to the Huawei shop at Melrose arch. The quote to fix the thing is 3 x more than what a new cost. So does this mean that your equipment only works until the warranty expires and the cost to fix is more than the worth so that we need to buy new ones. The call center phoned me, after I send this message to them, he told my that he will ask the service department to have a look to see if it was a manufacture problem. He said If it was manufacture problem that they will reimburse me. I was then told to come and fetch the watch. I went to pick it up. I asked what the fault was but they did or couldn't tell me. I have not heard from them since. Raymond Visser
