Compliant on undelivered order by debonnaires.

Hi again, I would like to inform you that my order was not delivered at Eersteriver restaurant. I kept calling them to ask for my order but their line were busy. I eventually spoke to an agent who was assisting me with cancelling the order and she confirmed that she was asking the store to cancel the order. After the call I went online to check if the order was cancelled but I saw the driver was on his way, so I waited and after waiting for another 20 min I called the store and the lady who was rudely assisting me told me that my phone was off and they are closing the store. I am trying to call your call centre but the lines are busy. Please find an amicable solution because right now the indicates that the food was delivered to me whilst I did not get anything. I don't know how many times I've bought airtime to call the store without any assistance. What's passing me the most is that there was no communication regarding my order being delayed I had to keep calling them with my airtime.
