Woolies and MTN: Partners in bad customer service!

About 2 weeks ago, I purchased a phone (Nokia3) at Woolies Sandton. The phone had to go in for repairs as it only worked for just over a week. The so called "Management" who committed to getting back to me has not done so in over a week even if its just to update me on how far they are with the phone. It looks like Woolies is learning bad manners and customer service from MTN. I expect much more from Woolies than their so called Partner.
