****py after sales service

Firstly I would like to make you aware that I am typing this entire mail using my middle finger. Today I visited your cresta mtn branch where I purchased a phone on contract. The speaker of the phone has decreased volume of its own. Upon visiting the cresta branch 02/05/2018. I was assisted by a lady named Whinkey.i explained my scenario and that the phone is not 6 months old,it was purchased on the 14th of December 2017.i was advised by whinkey that I should take my phone to Huawei directly and she wondered off looking for the address. When she returned I asked her why can't I resolve the issue here as my phone is brand new and I don't want it repaired. She then explained she can book it on, but needs my original packaging. I find it unfair that I being a loyal customer should endure being without a phone for almost a month, when it's clear a phone has a manufacturing defect. When I took a phone on contract I didn't expect to get gray stock. Mtn was to convincing when offering me a contract and promised me the world but unfortunately can't deliver on after sales service.
