Unhappy customer

(Popular furnishure store in midrand ) Poor customer service . I feel like I was robbed for not being taken through their laybuy policies. I made a laybuy in May for a couch and paid R1000 . When I go and cancel my laybuy due to being retrenched from the company I was working for. Its only then I was told I'm supposed to pay 10% of the original price of the item ,which was R700 . How is that possible ? I even asked to speak to one of the management teams ,I was told it not possible. I was given a email address for their support site. But the unfortunately the email is not working , I received a non delivery spam notification after I've tried logging in for a complain . I'm really disappointed and still cant believe this. Poor customer service and unfair laybuy policies.
