Not Paying my contract anymore

So where do i begin. I got an contract from Glo cell. They Closed and you took over. I took my phone in for repairs because its still under warranty. Surprise,.. They cant seem to find my phone on there system. No IME number on my contract. I gave the phone in to Tygervalley store and they said they will sort it out. My Phone went to your services department and Surprise they wont even look at the phone or give me a quote. They send the phone back to the store. I haven't picked it up yet. The tygervalley store didnt even try to make contact with me to let me know what was going on. i had to phone customer care almost 7 time to try and track my phone.But suprise no one can help me because they cant link my IME number to any divice. Plus redirecting me the hole time wasting my airtime on bull ****. When i start with end contract on these terms they just put the phone down.Plus on my contract there is no IME number. OK so now i am paying for a handset that i dont have. So i am NOT paying the contract anymore. I have tried to resolve this matter how many times and no one can or will try to help. So i am giving you notice that i wont pay one cent anymore
