Misleading Catalogues and Passing the Buck

After writing to Checkers HO to express my dissatisfaction with their advertised 'special offer' goods not being available, and their regular excuses of deliveries at a later date, not even an acknowledgement of receipt was received from them. My letter included a reference to a previous 'special offer' when we bought eggs and found three rotten eggs in the pack. Besides these problems we have constant problems at their tills with coding errors, and inside staff with poor attitude in responding to enquiries with courtesy. I spend far too much time at their 'help' desk rectifying errors and filling out paperwork to receive exchanges and refunds. On this particular day we were told by the manager to tell the cashier that Mr .... said they should allow me 2x500g packs of SR flour at the price advertised for 1kg packs which were also in the brochure and 'out of stock'. This caused a time consuming delay at the till looking for one supervisor after another to verify the sale - until I was ready to leave the entire load of goods at the till and depart. After arrival at home I discovered a double charge on a separate item had been made. (This I rectified on the following day.)
