Terrible Service

If I could rate it any lower I would, I recently got a new contract for data with them and the lady who assisted said she would add the data on my sim and didn't tell me that it would be for home internet where it needs to be in a router, why would you do that on a number you called as this is clearly a number I use on a daily basis. Now I cant receive calls and make calls therefore missing important calls, I am very disappointed in this service
