Disgusting Service during an extremely emotional time

First 2 important points: 1) I am a Government Old Age Pensioner 2) My husband is dying As my husband had only 1 pair of Underwear I went to the Pep Store at Ferndale whatever the center is called as I only moved here 8 days ago. I purchased the wrong size as this store had absolutely no system whatever so XL,M and S were all in a chaotic mess. Needless to say I discovered my mistake when I returned to the hospital and on my attempt to change them this morning I realised 1) I was not afforded the Right to Examine Goods, whereby a Consumer has a right to examine goods before purchase, and if they haven't done so, they can return them upon delivery to inspect them. o ******** Practices Invalid Store Policies: Any store policy or signage that attempts to override the CPA's imp**** warranty of quality is ******** and cannot be enforced. False Representation- there was not one sign in the store stating Underwear was not returnable nor was this stated on the totally blank side of the till slip! I am extremely angry, in fact FUMING MAD as this purchase is not what was needed and my husband is therefore denied the right to the smallest amount of dignity to have underwear on during this critical time which is a total disgrace so bow your heads in shame all Pep Stores employees, Directors, Managers, Supervisors and anyone else involved with Pep.
