Poor self serve

I've been using Capitec for nearly 7 years now and I never had issues. Recently I've been experiencing a lot of problems with them. To be specific, money that I've transferring have just disappeared into thin air and I am not taking about a few cents I'm talking about thousands of Rands. First instance my money was pending and now recently I have sent a R1400 to another capitec account and the recipient has still not received the money,over a week later to be exact. Another R3000 that was sent on Friday past, was also not received by the recipient. This is ridiculous, I don't know what's happening, a service that was flawless and effortless has now become a concern and headache for me. I have now lost R4400 that I don't know where I'm going to get to pay the people I owe. I am left with no money in my back account.
