Customer Service very poor

Having recently purchased Pick 'n Pay brand Frozen Spring Rolls, I logged a quality complaint to them on Facebook. This followed by them sending an email requesting detailed information which I completed & returned to them. An acknowledgement of received was received assuring me that I would soon receive their reply. A week later I am still awaiting some sort of response from: Vanitha Venketas Pick n Pay - Customer Care Consultant. I re-emailed only to get the standard acknowledgement of this & that a response would ensue!
