Afrti mobile ****merts

Debit order ran for 2 months perfectly after debit order date was moved. Mailed them in April to move debit order. Account blocked from yesterday, mailed them several times, no reply, send what's up to assigned number several times no reply. Tried phoning their CONTACT center with the NUMBER THEY SUPP****, number does not exist. Biggest joke of a company!!!!!!!!!!!!!
