Most people on the forum do try and give good advice... sometimes a problem does not have an obvious solution and several different solutions may be offered - not all of which will be correct/work
There are a few posts that are blatantly wrong/unhelpful but that is the nature of a forum like this and is difficult to avoid.
Please tell us what your problem is and we'll do our best to help!
Well people do ask u have u topped up the right way , are u sure u put money on u phone first, what's all that About, don't give me silly answers.
Because a lot of people don't give those of us who try to help much information, so by asking those questions we're narrowing down what could be causing problems for someone.
