Dishonest and very disappointed with their service

I bought a usb data stick last month and also purchased a 2+1 Gb data package. Within a week, by just reading and responding to emails, it showed me that my bundle has been depleted. I then went 4 time after this and bought the same data package every time. Last wednesday was the last time i bought a data package and on Thursday morning it was depleted! I contacted the call center, who said it could be due to signal failure, but i had full 3G coverage, after investigating further, i was told that i had over 6Gb left and one has already expired as its only valid for 1 month.<br> I feel that they are lying to their clients and that they create a false statement by saying that i was out of bundles. I have wasted money, which i so not have and i'm ready to take this matter to court! I want all my money paid back to me immediately and not for them to extend my data packages with another 30 days as i will not be able to use up over 6Gb of data! I've now sat without internet for 6days and cannot do any business, because they are busy \sorting it out"!<br> This is unacceptable"
