Bad Service

I bought Huawei cell phone from Foschini Hemingways which gave problems not even 7 days after purchase. I have since taken the cell phone back to Foschini 4 times already for screen freezing and not charging(which they take to Vodacom for repairs) and now on the 4th instance they telling me they cannot fix phone and it has corrosion and *****s that don't look the same. I have now been told to fetch my phone.<br> I am still expected to pay Foschini for the cell phone that is no working.
