No Help from MRP staff

I placed an order with MRP on Monday and never received any feedback regarding order so I phoned their call centre this morning. I am told(by agent Charles) that there is a technical problem and they will have to log the query and get back to me. The call centre supervisor(Virginia)says she will get back to me before 10h00, obviously this did not happen so I log on and chat to an online agent I explain the story to her again and tell her its already 11h00 I have not heard back. She(Maria) then tells me that they are working on it and they will let me know and she just started dealing with this query. When I ask why they did nothing about it 5 days and why none of them seem to be able to grasp the concept of service she ends the chat. Now seriously, who does that. Am I not a paying customer? Who infact already paid for something I never received. Then to get treated like this and cut off by a \ Call Centre Service Agent\" because she was done talking to me. Since none of MRP's staff members I dealt with today has any concept of service etiquette, I hope that there are some that can keep their call centre afloat."
