Just when I thought I was trying out a new network. I bought a new Huawei P smart gold at Westgate shopping centre. I am then told that I will receive 30 gig data once.off.so when I get I call the call center only to be told the competition /promotion ended on the 31 of Jan. So now my question is are customers being misled into buying with false promises.how does a sales shop not know that a promotion has ended 7 days later. How many of us are being mislead as customers . Let's not forget TCF. My contact number is ********** 014
