Abysmal service from Builders Warehouse call centre consultants

Absolutely shocking service from Builders Warehouse. On 16 February I placed an order online and when I clicked on 'pay' it returned an answer of 'payment failed', however the amount came off my credit card. I phoned their call centre to explain and was told to send proof of payment, which I did. Since then I have been phoning everyday - it is impossible to get the same call centre agent so every day I explain the story and every day I am told that they will investigate and get back to me, which doesn't happen. I have spent over R200 on airtime trying to resolve this and even drove from Fish Hoek to the Tokai branch of Builders under the mistaken notion that I could solve the problem by speaking directly to someone. Needless to say that did not help. I am deeply disappointed, to put it mildly, with Builders and actually feel like I am being made out to be a ****. They consistently tell me that they can't see the money in their account so refuse to credit me. I believe that they drag situations like this purposely so the customer will give up calling. This an unacceptable situation yet the staff are very obviously completely uninterested. After TWO WEEKS how can they simply keep on saying they will look into the matter and get back to me!! Builders Warehouse you need to get with the programme and look after your customers.
