Very furious client

Yesterday morning I made a cash deposit from an atm, few seconds later I received an sms money being reversed from my account, Ref :correction payment. I called capitec they told me that it's network disconnection and I must email the deposit slip they will resolve the matter in 1-2days. Mind you it's month end I need to use this money to pay my bills. Now they just credited only R200 out of the money I deposited. I am so furious because this is not the first time capitec is doing something like this to me in 2 months.
