Not happy with Impetha solutions

My husband and I bought a house and it was built by impetha solutions for 806k , 700k was financed by the bank and 106k was paid by us in cash, we were not happy with the finishes and when we complained nkosana dube threatened to sell the house we paid the amount 106k in cash without the finishes being complete because we had no home I am unhappy to say that most of the finishes are not done and it has been close to two months since weve occupied the house manicipality has cut electricity because impethat did not pay the water bill that they used to build the house we can not register with manicipality until they pay we have complained many times but into deaf ears the toilet bowls are unstable there many cracks in the house the water pipes are leaking garage door isnt functioning the list goes on and on yet we paid, I personally do not like the way they operate their business.
