Repairs 10 days and counting

The worst service I have ever received. I took my device in for repairs and the consultant who assisted me said it will take 2 to 7 business days but until today my phone is not fixed. It took them 4 business days to send me a quotation and I made a payment immediately because I don’t have any device that I can use in the mean time. 4 days after making a payment when I call them they advised that they are still awaiting parts. What do I do at this point since they have my device and I have paid for repairs? This is one of the worst way of doing business. Technologia group can’t help and Huawei can’t help as well.
