Edgars owes me money

On 12 Sep I made payment of R691.53 on my account which paid account in full. On 1 Oct then another payment was made via my bank for R689.00. I made Edgars accounts aware of this and inquired about a refund and have never received communication from Edgars to acknowledge my emails. I sent emails to [Email Removed] PLEASE Edgars - you do not hesitate to add interest on payments skipped so please do duly and refund me accordingly. I have sent you proof of payments etc including my banking details for refund. I do not want someone to call me to tell me that my account will be credited as I do not want to spend that money on Edgars. I will actually be closing this account following this. Looking forward to your response. Thank you
