Tiger Brands ***** pensioners cash without even a call

My 72 year old mother bought 2 loaves of Albany brown bread from malvern checkers on the 11 December and when opening it the next day we find its got whites spots all over and off. The expiry date is 12. Made several calls to their customer care that makes you hold till your airtime is gone. Asked repeatedly for them to call back. Even got other people to call them on my behalf but still no call back almost 2 weeks later. Tiger brands shows it is ********* and dishonest in its business practices and produce inferior products which is evident by the bread and also a 800g black cat peanut butter which I haven't even tried to call about yet. They don't care about their customers who pay them cash for their inferior products and have that cash in their bank accounts while they don't even bother to call back their customers who are pensioners and can't afford much. In turn they don't even offer you a refund of your cash but vouchers for more products that may or may not be worth your cash. Tiger brands does not value their customers and does not have their customers best interests at heart or anywhere in their planning. Disgusting service from such a huge company
