CSS Solutions/Brooks&Luyt are pathetic and useless

I have paid up my account and CSS Solutions/Brooks&Luyt fail to acknowledge this. This last installment only R648 was owed and you charged me R1000 and still have no acknowledgement that the account is paid off. Even Nedbank confirms that the account is settled, how does CSS Solutions not have any account of this. Are you people lacking in any sort of communication barriers and common sense? When your client proves facts you still act like novices. Where is my refund. Its pushing on two weeks now. I have made calls and emails and WhatsApp messages and no one has any interest in helping me. You people are so quick to demand money but when you owe money you run and hide? Your staff lack accountability, lack any customer assistance and are just pathetic all round. Month end is coming up and your agent can't confirm if the debit order will run or not. God help you it does. I've been told it has been escalated to the relevant "senior" department, nothing is done. Are they so senior that they're already pushing up daisies because I've have zero feedback and communication from this so called joke of a company. Pay me my money, give me my paid up letter and **** off.
