CELLPHONE NIGHTMARE

I purchased a cellphone at Donna Claire in Eastgate shopping centre on the 30th of December 2015. <br> within TWO WEEKS. The ''BRAND NEW' cell phone is now faulty.I called the branch in Eastgate to confirm if I can enquire at any other branch,of which they said I can,so I went to Springs. The consultants there were not willing to assist and kept insisting that I go back to Eastgate. I felt like a burden and unwanted in the store. However,I decided to call the store manager from Eastgate,who was very helpful and got them to take my phone in. 2 hours of my time was wasted unnecessarily at Donna Claire in Springs. The first hour being the day I handed my phone in and the second hour being the following day,when I went back to speak to one of the consultants for more information about my phone and a copy of my receipt,which again left me irritated and not well informed,in virtue of bad customer service and attitude..it has been approximately 4 DAYS and I don't have what I can call a phone,Which I find very unfair because its not my problem that the cellphone has issues. In the mean time what am I suppose to use?...REALLY THIS IS ABSOLUTELY UNACCEPTABLE!
