Cadbury PS Poison.

today i bought the CADBURY PS DUO. 60GR. at SPAR PARKSQUARE UMHLANGA RIDGE. and the Chocolate tasted like washing powder, i returned it back to Spar and was given a Telephone number to call: ***, which no one answered, sat at the long que. with no answer. im very angry with the Service recieved and disapointed i always buy PS Chocolates, and they never tasted like this. Spar said i should lodge a formal complaint and keep the Till Slip from them. now i have food poisoning from this.
