Pathethic Service

On the 08th of July my family had went on holiday to wildcoast Port Edward. We had ordered pizza from debonairs in wildcoast. When I had swiped my card it declined, but no declined slip printed. Wendy the manager insisted that payment did not go through. I questioned her as to why there's no declined slip. She had advised it's a network issue that's why it declined. Irrespective of what is the declined reason, there will always be a declined slip printed with a code as to why it's declined. Ii assured her that payment was received on my side. Payment did go through on my side. I am still awaiting a refund since then and still no one has contacted me. It's absolutely disappointing. The lack of customer service is very pathethic. They do not follow up with the customer. This was an error on they side yet myself as a customer needs to go running around trying to get some sort of feedback.
