poor service and false advertising

Just before Easters I received am SMS for Jet about a special they had on a phone (J4 core) you buy this phone for 1799.99 and get 1.5G p.m. for 12 months- but you have to recharge with R29 a month to get this deal. went to the shop Jet Galleria- to ask if this deal was true and it was. on the 30th of April I bought the phone. I have recharged numerous times I have not yet received the promise data. I have called the shop and there have tried to assist but they are tell me there are waiting for Vodacom … it is almost a month. at one point I was even asked to call Vodacom, I did hoping to get this sorted . Vodacom said I must send a sms to a number which I did... and still nothing till today. they shouldn't advertise things that they will not deliver on. now I a stuck with a fone that serves no purpose.
