Pathetic service

I have a business account with Standard Bank. For past three months I have not had anything coming into the account due to the fact that I gave birth in February of this year. As of March however some funds were paid in and understandably the account was in arrears for around 300 Rand which immediately got deducted. Nonetheless my account was suspended, without notifying me thereof. I went into a branch yesterday, got put on a phone & a consultant told me it would take 24 hours to unlock. It's been 24 hours exactly and I've just wasted 20 rands airtime waiting for customer services to answer my complaint. What pathetic service! It's not as if the money 'on lock down' belongs to them and what's ironic is the account gets locked but what they were owed they conveniently withdrew.
