Dont buy a smart device from FNB!

I am utterly disappointed at your services, on the 20th of July I purchased a Nokia 7 plus 11 days later i noticed a defect at the bottom right of the screen, it look like a smudge underneath the screen which cannot be wiped out. I contacted digital planet that is your middle man for smart devices on the 2nd of August and they arranged for pick up only on the 6th of August. The phone was sent back with the same problem two weeks later 22/08/2018. I called digital planet immediately and advised them that nothing was done to fix the problem. From the 22/08/2018 till today the 27/08/2018 They still don't know why the phone was sent back and just arranged for it to be picked up once again. I have emailed and requested for feedback on are they are going to replace the screen or give me a new device and no one can tell me anything.
