MBD and Sanlam unreliable companies

This company is all about making money for themselves they are not having interest into the people who are paying the money. They said I owe after sending them proof of payment then they never can back to say what they where saying about the unpaid monies. Sanlam will loose customers all because of this company since they said also that they will come back to me. Sanlam and MBD are partners in crime.
