service

My dad took me a contract out on November 1st. The consultant in the store advised that I will have unlimited data until March next year. I then received a message on Sunday stating I have used up all my data. I called in to the customer service line on two occasions stating that my dad will do the verification check and I will talk with him granting me permission as he cannot speak English. On both occasions I passed the phone to him to verify and the consultants hang up. I cannot use a phone I have for 16 days as I have no data. I need to get this sorted as I use my phone for business purposes. Can someone please help.
