Shame on you, Pick n Pay Melkbos

I received vouchers from P&G for a faulty packet of nappies. They sent me 3 vouchers to the value of R250 (around the same cost of 1 packet of Pampers nappies). I went to Pick n Pay in Melkbos to buy another packet of nappies with my vouchers only to be told by the very unfriendly teller that I can only use ONE voucher per packet. So basically forcing me to HAVE to buy three packets and having to pay in with cash for all three. And more cash than the value of one voucher. Then I ask that she speak to the manager as I was sent 3 vouchers to the value of one packet. Needless to say, the manager wouldn't listen to reason either, still insisting they will only accept one voucher per packet and that I must pay in the R150-R200 cash difference (depending on which value voucher I used). So I went to the nearest Clicks and they gladly accepted my vouchers for one packet of nappies. Shame on you Pick n Pay Melkbosstrand for trying to ****** money out of me by trying to force me to pay in cash what I could have paid with my vouchers. I live in Melkbos and would rather drive to Big Bay to Checkers to do my shopping from now on.
