Refund not being given full of excuses for over a month!

if I could give no stars I would as the service I have received from them is disgusying to say the least, I placed an express order and then had to cancel it as it did not arrive the day before I left on holiday. this was the 28th of October, it is not the 2 December and I am still callign in trying to get my money back from that order. to date I have had two managers promise to call me back with a solution and this has not happened , I have called in three times today and they are not able to tell me why I cannot get proof of payment on my refund and I keep getting the run around al they allow the call centre agents to say is we understand your frustration and sorry for the service. NO feedback being given and second month going on and no refund, I just want my money back I will not support this business ever, Shein has better service than this
