bad service

We have asked metro fibre numerous times questions about our account so we can sort out our account with them but they simply ignore our emails and never get back to us, they charge us fees never heard of and balance brought forward that we asked them to sent us statements and invoices to explain to us where all the charges come from but they never replay, the worst services i ever got from any internet supplier i ever had , i also have a 250 line but it is so slow i will swear it is a 25 line, if you ask them to sort your line speed they also never reply .
