Poor service continues

I complained about the shoddy service from Pick n Pay a few weeks ago wrt my tumble dryer. they have sent out a defy agent early last week. However, they have not contacted me since and I am still stuck with the tumble dryer. I refuse for it to be fixed (need a new mother board) and I know I may have problems with it if it gave me problems within the 1st 6 months of purchase. so now that I refused for them to repair it but want a refund, they have not even contacted me. Ridiculous! This is why the Consumer Protection Act exists, we are taken for fools!
