Woolworth's terrible product

<p>I purchased a cellphone, Samsung Galaxy J1 at Woolworths Centurion mall on the 12th of March 2017. Few weeks later I bought this phone it started giving me technical problems such as switching on and off, and whenever it vibrates, the screen becomes blanks, especially on calls where i cannot even answer my calls hense the screen would be blank and dying while on the calls. I then sent the phone back to the shop for fixing on the 31st May, then was given a date to collect it. I went to fetch the phone after 4 days as mentioned,on the 5th of of June, but the phone still have the very same problems. And then when i went back to the shop and they told me they will have to send it back again, and I find this totally unacceptable, unprofessional and no good service at all as I cannot survive without a phone as my work depends on it.</p>
