Disappointed and FRUSTRATED with the service!

<p>I've recently upgraded my contract and subsequently the monthly cost. Took for granted everything will kick in quite smoothly... not having any issues until SMS informing me of a credit limit activated and then suddenly no service, no signal, can't make calls, no data, nothing allowed from my phone... all I get is a message telling my account is suspended. WHAT. After sitting on the phone several times, each time the solution is temporary. I am so sick and tired of this inefficient and *********** service. Why can't the problem be fixed once and for all. Once again, the only way I am able to use my phone right now is because I have Wifi. What about tomorrow at work, or if an emergency occurs, what then?????? Everyday the same problem. Everyday I sit on the phone for hours. NO! This is unacceptable. I've had enough. </p>
