Bad Service

My bank account has been blocked from the 19th of March for a transaction that i don't know anything about. Consultants of Discovery Bank have said that it would take 48 hours to resolve, the next said it would take 72 hours to resolve from the 19th. The reason for blocking the account they say is for an amount of R5224 that a Standard Bank client has queried went into my account on the 2nd of March. I'm getting no feedback from calling them severally and their email is also not responsive. None of their consultants can see the amount they are asking about on my statement but still my account is blocked.

This is the same bank that offered me a credit card, but the credit has never been given to me regardless of my paying a monthly instalments on the credit card. I'm sick and tired of their silliness, I thought they knew what they were doing. I'm about to take all my accounts from them including my Life Insurance, I don't have time for this.
