Mweb-R799 Refund Outstanding Minus R199 D/Order?

After my first report to Hello Peter dated 06/12/15 about my Mweb saga, I received an apology phone call (gent) from Mweb, CT on 07/12/15. Second call same day from same (gent) I am advised that the R799 would be refunded to me. Phone call from Mweb (female) conveyed I could return the Fon Router to their Pavilion branch, which I duly did on 08/12/15, only to be told by Pavilion Info Desk, that the Mweb/Pavilion had closed down. This incurred an additional 30kms to travel to Mweb/Gateway! An SMS from this same (lady) due to her call being cut, referred to me by another name? Response from Mweb to my email query re non-refund on 14/12/15:- I understand that you are eager to get this processed. Your refund has been submitted. A refund of R600.00 should reflect in your bank account within the next 3-5 working days. We credited your account with R799.00. We deducted your January subscription from this credit leaving a balance of R600.00 which is the amount we will refund. No debit order will be submitted at month end as your January subscription has been deducted from your credit. Received an automated reply from Mweb to my email 15/15/15 conveying my non-acceptance of their actions!
