Lack of Service, twice!!!

I have been trying to get my case resolved since last week but no one has contacted me yet. Every time I call customer care the line goes dead! I purchased a data bundle of 1GB for R25 on 20 Sep 2021 on *** via my debit card and it was not allocated. I am now requesting a REFUND for this. I have sent an email to *** on 21 Sep 2021 and have still not received a response. Case number: *** Furthermore I have called in to query why my Vodabucks for Aug 2021 was not allocated. Yet again when I am transferred to the Vodabucks department the call is rejected. Please urgently advise on this as allocations took place on the 12 Sep 2021 and I have still not received my allocation for bill payment.
