Is Pick n Pay *****ing our money???

Hi often get PnP vouchers purchased for me from abroad.I never use the the complete voucher to its value because pnp can not tell you what the balance of the voucher is for eg. You have R100O voucher you use a R100 then when you back at pnp and you would like to know the balance they can not tell but rather have you embarrassed because there incompetence that you now have exceeded you voucher value. But that not my main complaint right. Hi received another voucher on Friday 4 November 2024.I used R120 at there liquor store and proceed to the grocery store to get some goods of remaining value of just over R400. As filled my basket with goods of R250 and went to check out the till that the voucher is no longer available becuase the balance is zero.I went to see manager and presented the liquor store slipp and the voucher code She tried help unfortunately not in-store. She mailed the head office all revelent documentation.The response on the mail was shocking!! Basically saying.. I don't know how to fix this I forward to someone who does. And that's where it stops. Now no one can help with this issue and my mails just don't get answered.All that remains to thought is they *****ing our money and I go back to my first for sentences. I have received many of these vouchers and never used them to there total value. What is happening to our Pick n Pay??????????? Resolve my issues!!!!
