Unhappy Customer

I sold my BMW 320i Motorsport to Lisabank Wynberg on Thursday (21 Jan 2016). I gave them all the paperwork including the Certificate of a car for them to do ownership. I was promised that payment will be made to me in 24hrs from Thursday, I called them yesterday morning to follow up on payments , Marla said it will be done during the course of the day ,yesterday. I then called again later in the day since there was no payment at all , several times where I was told that Marla was not available and left message thereof. I then spoke to a Lady, her name is Hilda, after a long battle to get hold of Marla. Hilda then said the payment was made already without checking the details whether it was correct client or not. Now I am not happy with the service so far I received from this Team, its Pathetic. Atleast update me to say Mr Ndlovu we are experiencing Technical challenges with our systems payments will be delayed by a day, I mean surely we will understand as customers. I need that cash to buy another vehicle which might be taken any time from now. <br> I bought this vehicle from them in August 2014 cash , I didn't even delayed to pay them, it was same time deal.
