Disappointed by miway

I'm so disappointed and frustrated on how miway treated me as their loyal client,I was under insured for my vehicle and when I do follow ups I'm being ignored I can't even purchase another vehicle since i still have sn outstanding balance that miway didn't pay,they insured my vehicle "Kia Rio 1.4 sedan 2015 model"for R142000 of which the market value of my car is R165000 they did notice as we that they made a mistake and a lady that gelp me with my claim by the name of HLENGIWE said she will speak to her supervisor and the remaining balance if R145000 will be paid to the bank it's been 3 weeks now and I'm now being ignored when I call and being transferred to one line to another I'm so stressed and frustrated ,suffering stranded since I don't have a vehicle and I need to relay on people to take my kids to school and also take taxis to go to work,
