Hot Cross Buns has Huge Flour Lumps

Firstly I've been a Customer of Woolworths for about 18 years ... I've been having bad EXPERIENCES with the Hot Cross Buns As for the last few purchases I've been Noticing that in the Buns there was huge flour lumps , then i Notified Woolworths Via E-mail with some Pictures I just thought No man there's a Reason why we as Customers do Woolworths it's Purely because for the Quality And we all no Woolworths doesn't come Cheap !!! Sadly Some of Woolworths Products are notup to Standard anymore as before ...... They then told me to come in-store and show them with Slips and Packaging And obviously who keeps all Slips and Packaging I then told them the Slips and Packaging is Irrelevant please Check with your Supplier or maybe it's the Machinery , Woolworths then Rep**** to my Email saying that there's nothing they Can do without Proof of Purchase , I then told them it's Not about the Purchase it's about the Inconvenience and a wast of my Money , Aslo told them if you can't find Proof of Purchase Please Check My Woolworths Card Or My My school Card Every Purchase should reflect on the Account ,they then sent me an E-mail saying we will look into the Matter and for the Checking of the Purchase they Not Allowed to go through Customs Accounts SERIOUSLY what BS is that Anyway it was Clearly a Loosing Battle Woolworths then said they'll be sending me a R30 Voucher , I rep**** to them Saying im Utterly Disgusted with Woolworths after all this back and forth you offering me a R30 Voucher Please give it tp Charity im Not a Charity case im a Customer
