Airtime purchase via the app pending

I puchased R150 telkom airtime on the cellphone banking app. I received an sms that the money went off my account but didnt receive the airtime. The transaction shows pending on the app. I then loaded a R12 to see if its possibly the network. I received the R12 airtime but hours has gone by and still have not received the R150. This is not the first time. In October 2018 i purchased R205 airtime and still waiting to be reimbursed. I ask that i please be reimbused for both transactions of R355. This is not fair, i have been banking with Capitec for many years. When i read others reviewes i see this is a common situation when purchasing airtime or data via the app.
