Wrong information

Good evening my heart is shattered I received a call in the passed weeks about a promotion of route home connect for 219 per month for 160g. I was so happy I asked the lady who called about how does it work she said it’s 160g for everything anytime, I even asked so there’s no night data cos mostly my night data I don’t use , she said no u use it anytime … I agreed with the contract but to my surprise I came home to no Wi-Fi on Friday telling me that I’ve ran out of data so I decided to call customer service today they told me that the contract it’s 30g day 30g night 50 promotions and another 50 for promotion was so sad cos she never explained non of this cos I was never gonna take it . I was use a cellc network for data which I paid 200 for 100g 50day 50night I feel so ****** by MTN for not being honest.
