They are terrible service company. I've been with them for 2 years. When I referred my friend, they doubled my bill than the usual charge. When I asked them why? They explained that I have a monthly plan and that is the price of the market. But my friend is the same and she got much lower rate than me. When I told them my friend rate, they said this is your rate and you cannot compare with the others. Then I canceled my account after 2 months. Later I found they did not give me the referral. They said because I canceled my account. But I canceled the account 2 months after my friend paid her bill. Don't go with this company. They do not have good service and customer service. The people over there are so rude. They do not take care of you. They are the worst I saw in Houston so far.
