Your bank when it suits them

Our account was overdrawn and we went to the bank explained the situation and explained that money would be coming into the account shortly. All issues sorted three weeks prior.<br> <br> Money arrived, account was put on hold, had to clarify where the money came from, had to supply the invoice and proof of payment from my customer, they contacted my customer to confirm the payment, embarrassed me and have put a serious doubt in my customers mind and after all that they say they are still investigating but can't explain what. Refusing to put me through to a senior manager and not coming back to me, I have to phone and ask and I get nothing in return. They can't even tell me how they or when they going to sort it out.<br> <br> We have had lots of money in this bank but yet we are treated like *****s. It's actually a totall disgrace and as soon as this matter is sorted we will be looking to move our accounts.
