Poor service - Consumer Complaint for INCREDIBLE CONNECTION - HEAD OFFICE

I am really upset with the service I am getting from your store ,I sent in my device for repairs in February its been a month now I am receiving any feedback, I call and they promise to call me back but never do, when I go in store they still say they will call its April now it's over 21 working days please bring back my device or give me my refund, the service I'm receiving is unprofessional and is affecting me as a customer.
