Bad after service / Return Refund items

Zando's after service is pathetic. It has almost been 1 month and I am still waiting for my refund for my return items. I have send email and spoke to consultants but have only been promised ,that it will be sorted but I am still waiting. I called this morning 21/12/2015 again and was holding on for someone 15 minutes and eventually when I got to speak to Luke he puts me on hold again for 5 to 10 minutes and just came back it will be sorted by end of business today. I got an email at 15:39pm \We have received your return and processed it at our warehouse. You have requested a cash refund which is currently being processed. Please note it can take between 3 and 7 working days for your refund to reflect depending on your banking institution and method of refund"Last week Tuesday I spoke to someone at Zando's regarding my query and I got this \""We have received your return at our warehouse and will inspect the goods before processing. <br> Please allow a day or 2 for us to process this for you. You can also track the status of your return when accessing the \""My Returns\"" section on our website while logged in\"" I am very disappointed. I want someone Manager to contact me urgentl"""
