Waste of F#ckin time!!!

I called Woolworths with a complaint on the 25th September 2018 and was told to email the evidence to them. A week later I called them and was informed that the matter had been concluded. I received an email on 1st October 2018 with the outcome and 2 SMS's with 2 gift card numbers on 4th October 2018. I went into the Westgate Mall branch on Saturday and after trying four times the gift card number declined. I then spoke to customer care and was told to call back or go to the store Monday. My question is who pays for my time, my fuel, my call charges? Is it not their responsibility to check that the information is correct before issuing? Now I have to drive up and down for something that is not my fault. This has been going on for two weeks and it is unacceptable. I felt humiliated in the store, being showed away after 15 minutes in the queue! I could have spent my time on better things.
