Hinen South Africa

i got into contact with a Agent Roald. That helped me with a Solar system rent to own. He sent the docs i signed and agent then promised me they sending stock to cape town as they based in sandton. The product arrived last week Wednesday and installation was verbally confirmed for saturday. Saturday the installing company called me they cant install as stuff still needs to be bought and the contract is not valid due to the esign and then printed the contract yesterday and sent it in verbally again wednesday we will install . Today i got a call they cant install tommrow as Hinen south africa is no longer doing rent to own . Please explain this to me as this is highly unprofessional and contract has been signed what do i do now. Hinen SA Super unprofessional
