Old fashioned Fish and Chips Steeledale branch

I was shocked with the tiny piece of hake bought from the Steeledale branch yesterday by my 94 year old mother for her supper. I was with her and asked the shop assistant if this was correct. I was given the name of Lindiwe and a contact number for my complaint. The regular size hake cost R27.50, was as small as a R10 note and weighed 50 grams!! I feel that my elderly mother was ********** but the staff insisted it was correct. I took photographs of the piece of fish and the till slip because I could NOT believe it. I will not support this franchise again
