Discovery bank harassment

Discovery bank

Called me regarding an arrears on my credit card

I said I would address it in the time discussed

They then continued to send numerous messages despite an agreement in place

And even worse have done something to the account that’s not allowing me to deposit into it from my normal cheque account

So here I am being harassed despite having and agreement in place

And further to that I can’t settle the matter because

I can’t transfer cash from my discovery cheque account into the credit card

Absolute shambles
