Huawei customer service I have send my phone in for repairs it was supposed to be repaired by the 28/5 yesterday when I phoned I spoke to a guy by the name Quincy no they are still waiting on stock really how can a company give an estimate time and they can't keep to it and that is a customer service of Huawei and on top of it you must first pay them and then only they fix it really
