bad Item Service

<p>i cancelled my contract few months ago, everytime i charge the mobile Hisense (HS - U601) it reaches 100%, immediately i pull the charger from, battery just goes straight to 0% rapidly.</p> <p> </p> <p>Ever since i cancelled my contract i have been experiencing this problem, which suprisingly i never experienced before while i was paying for the contract. To me this is all "coincidental" which is irritating me. i cannot use the mobile now simply because of that.</p>
