Nothing but dissatisfaction

<p>Since i've got my Samsung S6 contract in april 2015, i have had nothing but issues. </p> <p>THe issues range from Cell C debiting me the incorrect amount for months, my phone having absolutely no network coverage for days at a time, my phone having to be taken in for repairs due to the screen malfunctioning ( and then not to mention being given a replacement phone with a battery that didnt work forcing me to only be able to use the phone while plugged into the charger) and now back to my phone having no network coverage.</p> <p> </p> <p>My phone has had no network coverage for 2 days now. Cell C says there are no issues in the area that i am in yet my phone is still not working. What is the issue? What am i supposed to do? When is this going to be fixed and how is it going to be fixed?</p> <p> </p> <p>I need this issus resolved, i need to know why i have no network coverage and i need assistance ASAP</p>
