Huawei Canal Walk Complaint

Huawei Canal Walk Complaint: I took my phone to this store to fix and was told I needed to pay R2200 upfront which I did. Following this I was informed that the phone would cost R4900 to fix due to other defects that were identified. I requested that it be cancelled which they happily accepted. I provided my banking details for the refund to be actioned and was told that I have to wait 7-14 days to wait on my money! I bank with FNB and so do they. Why must I wait 14 days for my money and for a service that wasn't rendered! Banking details sent on 8th June and still refund has been actioned.
