Pick n Pay Poor Service and Training

I have had the worst experience at this business ever. Last week I bought a branded food item and discovered it was stale. I returned the item and exchanged it for another. Only to discover that this item was also stale. I returned this item Fri 13th and showed them that the packeging was cut and damaged. I asked for another but of another flavour as I believed that this batch was faulty. They bought me the same. I used the words "that this is BULL****..." and the young manager said he does not tolerate this language and that I must not swear at him. Thwn he told me to leave the store and was quite condescending as he carried on in front of about four staff members. I became very angry and had to walk out the store to calm down. Thereafter I walked back in the store and called Pick n Pay customer help line. They said they would escalate this matter to their Regional Manager who up until now has not bothered. This happened about 1.30pm today.
