I made a review last week in regards to the competition I won and never got my prize . At first the lady who phoned me told me that reviews from Peter should be about the products. She then gave me C***** Sip up marketing contact numbers . I tried several times, and they never picked up .The competition was even televised on national TV. It was a buy to win competition. I bought the product and I was fortunately to win a grand prize.I've sent my quiry to their socials verified pages . For the past years, it has always been that we will send your quiry to the C***** Sip up marketing team. I never get feedback.
