Bought Huawei P20 and Vodafone SIM last week. Purchase experience very good. Returned to store for some support as previous phones all iPhones. Appalling service from operative who a)couldn't care less and b) had no idea about Huawei. Came away totally dissatisfied. By contrast when I went to the Vodafone store opposite, having been told they would be hopeless, could not have been better served. Indeed, work colleague was of more help and had considerably greater knowledge than CW staff. Quick to take my money, unwilling or unable to assist after the event and despite promises didn't come through on Huawei earphones offer either.
