TELKOM BAD SERVICE

I purchased airtime yesterday on my Capitec App and it was " successful " loaded but I didnt receive the airtime, i called both Capitec and Telkom,Capitec they need proof(Invoice billing) and when I called Telkom to ask for this, they then said they airtime doesn't reflect on their system, I then asked them to email me the invoice,I haven't received anything from them,I dont know what else to do.
