Bad service

I went to cellucity canal walk in August 2017 to upgrade my contract. 1st thing - my contact ended in November I just went in to store to check when the upgrade is due they upgraded me in August and double billed me up until November I was so broke as they did not advise me of this. If they told me I would have just waited for November as I needed a cheaper plan. 2nd - they advised that my contract will stay as is so I will still get my 500mb of data as I told the guy I don't make calls u just need the data he said yesss the special they have now is that 10gb for first 3months and 500mb there after I was to impressed. After 3months I only got airtime 200 and no mb I called them they advised that my plan only had 10gb for the first 3months and no data after like *** who buys a smart phone with no data.after I told the guy over and over. When I called the lady said oh shame they propbly just wanted to make a sale.

3rd- I was advised that I have tempered glad on my phone so when my phone fell I just went alone and bought new tempered glass as I'm replacing it I see that they did not put tempered glass on my phone the guy just put on a thick plastic. I wish I had enough money to just cancel this contract this is by far the worse service I received. The worst part is that everytime I complain they say I have no proof. So ARe we suppose to record every convo when going into a store as I trusted the agent that was helping and its not like I wanted the stuff for free.
