CellC Date Stick

<p>I've had my CellC data stick for a while now and was always happy with it's performance. But of late it is as slow as a snail. At times it won't even open the Google home page. Mostly I log in on the night time slot. I have phoned in numerous times to complain but still the problem persists. Can you please do something about it or tell me if there are new drivers that I don't know of? I am contactable on the number ********** </p>
