steal money

so for about 3 years now i have used Q4U secunda for my 2 cars, and all went well up until i tried to get my cars licence disk done again.. i made the appointment for the 23rd of December, paperwork was picked up as per usual... the next day i recieved a whatsapp saying the licence was done and would be delivered.... my licence however was delivered on the 3rd of January ( not too much of a problem for me tho)... when the licence disk was delivered i was informed the person doesnt have my change with them.. i asked on whatsapp what is going on and was informed that my change would be paid over via EFT, i sent my banking details through and was told it would be done immediately, it is now the 12th of January and still haven't gotten my change yet, no is answering on whatsapp and no 1 is answering their phones at Q4U... i have already informed friends and family members who also use Q4U's service and was told they too have experienced similar problems but also only recently... unsure if there are new owners or what has changed, but their service went from excellent to well basicly just stealing money.
