Warranty Policy Transfer during private deal

Bought a car from private seller. Car has Warranty policy which expires in 2019 and service policy which expires 2023 and dent and scratch exec expire 2018. Innovation group requested us to fill transfer documents. After completing all relevant documents and submit I received automated reply stating updates will be done in 72 hours. Week later I called and was told warranty policy was cancelled(NB Seller settled car when I bought it). Informed seller and she called and her surprise the policy was cancelled. Innovation group (Howard person she spoke to) claimed it was an error from (Lando) and would be sorted out. Nthabiseng Rantsieng (innovation group administrator) promised to action transfer of policy. 21 days later still not done. When I called and after holding for 30 mins as usual, I was promised a conference call with Nthabiseng. Conveniently called got cut off. This requires attention and advise on the way forward. Policy still not transferred. In turn I was also sold a policy and when I realized that there is an active policy I cancelled my policy.
