Amobia lack of comunication for prospective client

I have recently being trying without sucess to get hold of amobia via e-mail as I am out of airtime for the month, I did speak to 2 people the other day in regards to a site survey and instalation was told they would get back to me as of yet they have not, I have sent numourous e-mails requesting information about a 4 meg uncapped internet service, I am tyring tto find out the fair usage policy and at what point will my speeds be throttled with peer to peer downloads and skype calls but as of yet I have had no feed back, I have bieng searching for almost a year for an alternivive to adsl in my area as there are very few options avalable to me and telkom does not provide access to my area so far I am unimpressed with the service
