They said sms that is a hoax

I know that I'm the one at fault and desperate they ****. I opened an account for someone in my name, the person never paid it. I except that this is my fault. I am a single mother that work 7 days a week to survive, I don't have the money to settle the account. Lat week I get an sms that I can get up to 70% discount if I settle the account. My brother agreed to help me, I call them to get the settlement amount, they tell me oh no their is no discount offer for you. Why then send the sms. This is entrapment. A big company sending sms under false pretenses.
