Not receiving any help with this bad service!

<p>Over this last two months my billing was very high and I would like to find out why, but since I've logged a support call on the web site (twice) on Thursday May the 4th I've had no reply. I have then tried to log a support ticket with a support agent on the GloCell Facebook page where the support agent rep**** an agent will get in contact with me, but a day further noe reply and I left another message on the Facebook page ( seems to be the only place one gets an answer if you lucky because getting through on a landline as a nightmare because you get cutt-off and when you can speak to an agent the backgrounf nouse is very loud and you can not hear anything) and after a long while an support agent rep**** they will follow up. Today is now allready Wednesday the 9th of May and still no reply!! My query is simple, why was my bill so high each month? I believe it was because of over billing but I can't get a response from anybody! My reference number - ********** 2</p>
