Gift Voucher Dilemma

What an appauling service rendered by what I used to consider one of the "best" stores in the country!!!! My dilemma started when we made a bulk purchase of gift vouchers worth R7000 to use as an incetive measure. To my shock, it turns out that one of the vouchers (which was already handed over to the intended recepient) was reversed during the transaction. This was discovered after relentlessly calling their customer care for assistance which fell on deaf ears. Eventually, I was given Delmain Newkirk's number who confirmed the reversal but blatantly failed to provide a way forward or resolution after numerous follow up emails!!! Forwaded the slip confirming payment of the card in question to no luck! Decided to call the customer care once again only to be provided with yet another number which lead me to nowhere (in this case, "nowhere" refers to Easypay). Spoke to numerous people, Zenobia, Nadine etc. Over and above the embarassment suffered by the card receipient when trying to make payment/purchase, the inconvinience of being sent from pillar to post and not receiving any kind of solution is extremely disppointing! This I would assume should be the easiest rectfication a prominent store like Pick n Pay can embark on or at least create a seamless process for! Sick!
