Customer care call center has zero follow up or resolution

on the 24th of Jan I called their call centre regarding cheese purchased at one of their stores that expired at least a month before the Best before date. I explained to the consultant i do not frequent the area in which i bought the cheese and therefore could not return directly to the store. She practically told me there is nothing she can do to assist me unless i return it to the store at which it was purchased. After a long debate she agreed to assist a log a query, She asked me a list of questions which I answered and then eventually I explained to her at that stage my telephone call to the call centre (from my cell phone) was way more expensive than the cheese i had an issue with and asked if we could end the call. I was sms'd a ref number but a month later I received no further contact or follow from pick n pay. I would let this slide if this was the 1st time occurrence. However about 3 years ago i went through the same process regarding a different product and years later I still have not heard from them.
