Very Misleading , Upsetting and frustration

On 28 December,2018 i went to upgrade my mobile contract for a new mobile which was a Samsung Note 9 512 GB. I was promised by the salesman by the name of Le Roy that he will organized my the 512 memory card which to my knowledge comes with the fone to make it 1 terebite as advertised on tv. Every day i have been calling MTN and up to now no response and my 14 days is over as per the contract conditions. If i was told that the fone comes without the card i would never have taken it as i am using the fone for business and not for pleasure. I was offered in return a wireless charger on which i refused and then a wireless headphone which i also refused. The Samsung consultant called me on Friday 4th of January to tell me that i cant get it as it was a promotion when the fone was launched but he will speak to his manager and see what they can do and will call me the next day which never happened.I have made numerous calls to MTN and it was said to me that the store manager will call me and up to now nothing happend. Why dont the salesmen be upfront with their customers when you want a fone with certain features that its no longer available as if i was told this in the first place i would never have upgraded to this fone and for a customer since the 90's when cellphones was introduced i have been a loyal customer through my company fone until it was transfer over to my name up till now. This is very misleading whether from MTN or Samsung as this is not on. I would like MTN to sort this out as i will go to the consumers protection and ask them to do something regarding this. Thanks.
