False advertising

I understand wrong printing but it goes along with false advertising. The Samsung GalaxyA8 contract deal was for R165 X 24 months and when I asked if it was in stock they said it was...only to find out that it was ONLY for prepaid of R7999. Then only do they say head office printed it out wrong. The special went goes on from 19 April to 2 May. And if I still want it on contract it will be R399?! Only then did I get an apology for this false advertising, I'm not impressed at all and I had to call countless times before being set straight. I want what I saw on the advert,I'm dissapointed in this store.
