DON'T use this network. It is completely insane and it drove me crazy. I currently lost my phone and I need them to give me a PDF file about my usage details. At first, I contacted their online agent online, they asked me to send them a letter, together with a 10GBP check, so they can do that for me (AND it will take 40 days, which is INSANE). And I asked can I do it by email, they said yes. (So what is that 10 GBP for if I do it by post? They didnt explain to me even I asked). So I send them my details in order to get that PDF file. They told me I have to wait 5 working days. So I asked them on 9th and today is 15th. I got no reply from them even I asked them on 13 and 14th, when will I get the PDF, they COMPLETELY IGNORED me!! What a customer service. I will never use them again and I will ask my friends not to use them!
