Warranty changed over night

Good day

My name is Thulani, i reside in secunda Mpulanga i would like to share with everyone the bad service and the warranty that changed over night with my Service Provider Vodashop Secunda Mall. I signed up for a new contract on a Huawei P8 Lite device on the 23rd of August 2017 and when i got home i had a change to go through setting up my device for functionality, whilst on that i notice that my device had a green line showing as a dead pixel or art effect at the side of the screen unfortunately i couldn't go back to the shop the following day to file my complain, and only on Friday late afternoon i went to the store to ask some assistance on the factory fault i discovered pertaining my device. ********ly i was dismissed by the vodacom stuff telling me that they will have to send in the device to the Technicians to be checked i was shocked as these ladies didn't even bother to inspect the device for physical damage on the device. It has just been a day and a half i have had the device still on it's plastic protection covers with not scratch or what so ever, this was so *********** and bad service practice looking to the fact that they just sing the warranty terms to you but they don't understand them. Now my question is what do they meant by saying "if anything goes wrong with the item purchased withing the period of seven it will be replaced with a new one". clearly it seems like we don't know what we doing here. And this is totally a complete bad service and lack of interest to their customers...........
