Rip off prices and portions

Ordered 2 Cheesy Toasties from Modderfontein branch on Monday 10th August. They were R45 comprising 2 tiny sandwiches, hardly filling and tiny. We were most dissatisfied and still hungry. I emailed Lexi's to complain and despite a nice explanation refused any compensation or damage control. I feel this is unfair as they are not interested in customer service
