Please advise ..

I bought R70 airtime and 2g data for R140 on the 5th May 2020. Both transactions went off my Capitec banking app. Capitec says Telkom says ive paid and received the airtime and data. I DID NOT. Can someone please rectifying this???? Its the second time in a span of 7 days that I have this problem??? Big companies Like Capitec and Telkom wants us to use their apps for CONSCIENCE but ive just experienced INCONVIENCE....
