Pathetic after sales service

Let me stat that this is my first purchase of a huawei phone...namely the huawei p9 .as it is an leading brand in cellphones at the moment they are definitely not leading in after sales service. Having previously purchased other brand phones.I have never received such un cooperative service as I am currently receiving from the huawei service centre Melrose arch.you must be wondering as to why I am so disgusted. So here goes with my entire story.on the 08 June 2017 I handed in the device at wefix pavalion Durban for repairs to a cracked screen ..I was told that the have no stock on parts and I should wait for parts coming from abroad..I then decided to phone the service centre in Johannesburg with help of getting the device fixed faster...we then tried to arrange for a courier company to collect the device from me...I was then told that the courier company is offline.. This carried on for weeks until the 20 July 2017 when the device was finally collected from me in Durban it is now going over a month and I'm being pushed from pillar to post regarding the delivery for the device..I asked for a supervisor by the name of "KJANELO" to call me a dozen times and seems like the supervisor and service centre guys have a don't care attitude towards customers they don't reply to emails neither do they return calls
