Terrible experience no refund from RCS

Terrible experience still waiting for 3 refunds been 2 weeks. No one from rcs is even phoning me. I spent all my airtime on calls to RCS. Sent over 50 emails with Proof of deduction from account an no orders processed. I spoke to several agents who did not assist me. Sent the same emails to several agents an still no refund. I'm a single mum needed groceries urgently but unfortunately I have been ****** for over 900 an it's almost pay day so I will have to pay full amount although rcs didn't refund me.
