I entered a competition at Spar buy 2pkts of halls and you stand to win an airfryer. I received a call on the 6/8 advising my name was drawn as a potential winner ? I had to send a photo of my id , which I did on the 6/8 - I have been following up for 2 weeks now !!! With Spar Head office , the company controlling the competition with.no success !! Really !! I have my till slip , I entered etc and you contact me and don’t come back to me ……
