Complain

The manager was rude and treated me like am not human they priced the sugar wrong a 1kg for 11.99 and he is yelling me I can't have it for that price cause is 23.99. Consumer rights what happend to that. Iam very disappointed and I didn't know ****** still existed till today the old lady helping me went to double check the sugar with me bt was terrified to tell her manager. With the name tag JP.
