***** or Violation of the POPi Act

So today I opened my post box to find a letter from Truworths, in the envelope is a black card with my name printed on, congratulating me for being chosen for a R4000 credit account, I have never app**** with Truworths and I will never ever in the future, this feels extremely *******, the fact that Truworths goes through the effort of printing cards and sending it out to people's homes to try and get them to make debt is absolutely disgusting even worst that you have my personal details, I farely new home address, so I would like to know where Truworths got this information as this sounds like a direct violation of the POPI Act, I need anwers from Truworths because this is unacceptable.
