Charged for irregular usage on wi-fi device

Please call me back asap. There is a discrepancy on my account. I only used it once where I literally switched it on and try to connect my daughters laptop and my smartphone to it yet I was debited R449.00 in June and the consultant told me that there was usage of over 3 gigs which is impossible because I had lost the password and never ever used it again.<br> <br> The consultant I called confirmed there the sim card is in use, with usage as recent as the 30 June 2015. This is HIGHLY impossible as I never even took it out from the box after I had misplaced the password. He refused to issue a URL report so that I can see what sites were visited. This is ***** and I will take it up with ICASA.<br> <br> I will not pay for irregular usage as I have not used this device other than switching it on ONCE.<br> <br> Please look into this as the deal I signed up for is R99pm - I cannot afford R450 per month especially for data that I have never used<br> <br> I am so disappointed in the service from Mweb!!!<br>
