Pathetic service & ripping off customers!

The manager and employees are unprofessional and not polite to the customer. Service is desperate, and they are ripping off customers. There are no notes on the door that they would not cut the deli to customers 30 minutes before closing a shop. Today I came to the shop at 17:40, and they refused to cut the ham into slices as all cutting machines were cleaned. I took two pre-cut packets, which price ripping off the people as the freshly cut chicken roll costs R 129 per kilogram and this packet one R 170 per kilogram. I requested them to weigh the mass of the pre-packet, and the gross mass (including) plastic is even lower, about 5-10 g, than the one written on the sticker price. The sticker price for the chicken roll packaging was written that the content was tarred. This is not true. If the content of the package was tarred, then the gross mass is supposed to be more than what is written on the price. They told me that the higher price for prepacked meat is due to the packing, which is about 31 %, but customers still have to pay an additional charge for the plastic that was not deducted before putting it on the shelf for sale. Some inspectors/auditors need to go there to inspect the quality of their service as this type of service is so pathetic.
