Wifi data drained AGAIN

<p>Good day,</p> <p> </p> <p>I recharged with 3G data on my wifi a week ago. 3gig lasts me 15 - 20 days. This was drained in a week. That is impossible as I didnt use my data more than usual or downloaded anything. This is unacceptable. Since I got this wifi router I have data disappear on a regular basis and use more data than ever. I dont do anything different than I did before I had the router. I want ny missing data replaced. This can not continue. </p>
