Pathetic service

I need feedback back regarding my application process Here is my reference number : RCO507611 I am getting such a pathetic, poor service from Mondo Mobile. They called me on the 21st of March to offer me this a product and I agreed gave them all my details on that day the phone cut, they NEVER got back to me. A week later I called them they still needed more documents after I had already emailed the documents to them. Till to day they have not called me back nor even communicate via email. I called them on Monday again, they advised and promised they would get back to me on Wednesday 10th April today is Friday and I still called them this morning only to have a sales consultant pick up the phone and put me on hold for more than 10minutes. What kind of service are you offering? What exactly are you doing? All I actually needed was yes we can assist you or we can't that's just it. 15 days later and still no response still on resolution what must one do now. They don't even respond to emails????
