DONT LISTEN AND MWEB DOESNT CARE

I signed up with mweb at the end of last year. I was slapped with an account of -+R2000. I opted for 2GB contrat as I don't use the internet every day and only log on to the internet when I am using. The last 2 months again I am billed with an exorbitant amount. In January I specifically told the person at the call centre that I never wanted to exceed R 100 of data. I was told that a soft hold would be placed on data bundle. I have phoned the call centre numerous times and have emailed the billing department 8 times. You get a reference number within 24 hours, but you never get an answer. I have also asked for itemized data usage and still receive nothing. I previously would by (cash) 12 months data bundles and the strange thing is that I only ever exceeded my 2GB once. My standard usage was 1-1.5GB per month. <br> When I contacted the MWEB to complain about the exorbitant data usage I was told that somebody has logged in to my wifi and can also access when the modem is off!!! Can an IT guy help with this???<br> <br> I am on permanent disability and have to watch my expenses.<br> <br> Please help
