No payment after 30 days

I have been waiting for over 30 days for a Payment made to my account, every time I contact the bank they told me to check with the sender and the sender will do payment verification, after many attempts in all channels I got a missed call for the first time from Capitec bank and the company the send the fund informed me that Capitec said they can't get hold of me to do verification on my side, this is one missed call after 30 days , I returned the call and the number don't go through, this is the worst service ever, why must we suffer for our money.
