Poor customer service !

I am appalled and intensely exasperated by the disgusting service received from Lindt at the Pavillion in Durban KZN. I have visited the store multiple times as I really do enjoy the chocolate milkshake. In the last couple of weeks , I came into the store requesting the shake , to find that there’s multiple being made, just not for the walk in customers. The lady that’s in charge of chocolate tap / milkshakes has such an attitude. I’m not sure if she owns the store or she doesn’t want us to purchase the shake , or if she’s just tired of life. She never smiles, isn’t courteous, just incredibly rude. This is really bad for business. After constantly being told that the milkshake is not available, I did mention politely that this was a bit upsetting. On my visit today , she remembered me saying that this was upsetting previously, and took extra long in the back room before she came to the machine to process my order. She didn’t even check my receipt , just pushed the shake towards me with no smile or a simple ‘hi’. I tasted the shake and it tasted very weak, as if there was more milk and less chocolate. So I proceeded to go home. Two hours after having the shake , I felt nauseas and vomited the contents. I’m flabbergasted with the service and now the product ! I’ve always enjoyed getting lots and lots of Lindt for the family and mentioned to a host of friends that this milkshake is the thee best in town. I’m really sorry , but my good reviews have now been retracted. I’m warning my friends to please keep away from Lindt , don’t want anyone receiving this disgusting device.
