Appalling service from Old Oak Spar

Spar Old Oak is the worst store ever. The manager Hennie is rude and uncaring. I've spoken to him to lay a complaint regarding the overcooked chicken and old hard chips sold. The staff said that the reason for the bad service was because the cook is on leave, they replaced him when an unqualified person. My complaints are being ignored and I'm still waiting for the "manager " who does not respond to emails to get back to me. Appalling customer relations.
