Cash send ISSUE

I made use of the cash send app on 29 June 2020.. the transaction duplicated without being able to redeem the voucher or money being reversed back into my account. I called capitec immediately where I have been advised about a glitch on their system and monies will be reversed automatically. The next day 30 June I called in to log a formal complaint on these 2 amounts.. I have been following up...been promised call backs...nothing the issue is apparently with the ''SUPPORT'' group but every time I call they escalate the issue to this support group...eventually I received a sms that 1 of the vouchers has been credited...WELL DONE... I call the same day advising only the one transaction was credited what about the other one now, I got told that they will escalate to support again. I called this morning again and guess what know one knows about the second transaction they don't even have the voucher number , this was never escalated ..im begging for my own money and waiting for call backs that never happen....CAPITEC YOU FAILING ME BIG TIME its 20-07-2020 today please priorities your customer queries
