Stone Age Pep Cell needs to get with the times

Pep Cell uses 2005 methods in 2018, seriously! What happened to moving with the times? I bought a decoder THREE WEEKS AGO and it doesn't work anymore. Now I have a three year old and till slips and boxes are bound to be torn up but because we're in the technological era you would expect that my purchase could still be tracked by my decoder number or smart card number (This only makes sense) but clearly common sense does not exist at Pep Cell and now I wasted hard earned money for nothing and they really don't give two ****s at the store, they just brush you off when they've already taken your money but they forget that if each and everyone didn't buy stuff there then they wouldn't have jobs, fundamentals of customer service! I'm so disappointed I won't even lie
