Very disappointed in the overall service

First of all, I placed an order on Tuesday evening last week, expecting delivery on Thursday. Waited all day, nothing, emailed them, nothing, emailed again on Friday, as my daughter's birthday party was Saturday. No communications from them. Then Saturday at 3.30, while I had guests, the order arrived. I put it in the fridge. On Sunday I repacked it for my freezer. As I weighed it, I noticed that each and every pack was under weight. All in all on a R800 order, I was half a kg short. I then emailed them to let them know. Till today, no communication from Fairfield Meat Centre... I am so disappointed! I am a single mom, and this is a big loss for me... Prices are so good, yet I cannot trust them any longer...
