This company departments have the most pathetic workers....the information given to a person are incorrect.I have been struggling since the beginning of the month....3 calls....all 3 calls incorrect information given.now after being told on a phone call tonight to them that they need authorisation frim our bank to rerun debit order I go and draw the money cash to them and what happens They RERUN the debit order.I would like to know who is going to pay those returned debit orders after your consultants incorrect information.Your calls are recorded I will give you the dates of calls and times and you listen to your consultants advice and show me im in the wrong.this company needs to come right for I am for sure one person going to cancel all my contacts.It us pathetic.you guys are quick to give out contracts but your after service and assistance causes damage to your clients.
