ABSA Appliance Warranty administrator incompetence

I have an ABSA Maxicare appliance warranty for several years. This warranty is administered by the Innovation Group. In July, I was charged my normal policy at a reduced rate and I was charged for a policy that I never took up. I contacted Innovation, and I received a refund for the incorrect policy collection. In August, I was not billed for the normal policy that I had. I contacted Innovation again. I was told they were aware of the problem (no communication to customers). They then collected the policy from me. In September, I received another refund for the refund already received in August. I contacted Innovation again - the answer I received was that the refund is correct. I stated it was duplicated. I was reassured it was correct. So where to from there? This month, I expected no problems. Surprise, surprise, Innovation collected a premium, but at a reduced premium and not the normal rate that I used to pay before July. Now I am sick and tired of dealing with Innovation, although the lady trying to assist me has been fantastic they simply cannot get this right. ABSA, they are bringing your name into shame.
