Audi South Africa - Beware of Motorplans

My Audi Q3 is still under motorplan. Last week I arrived home after 30 days away and the car would not start. Audi responded and within an hour was at my house and established the battery was flat. They jumpstarted the car and drove it to the workshop in Somerset. This battery was but 4 months old having been replaced previously under similar circumstances. I have now been without a vehicle for 6 days without even a single courtesy message from Audi indicating the way forward. I today called the workshop and Audi now maintains that I have to pay R7000 for this repair (R4500 new battery plus R2500 installation - what a *******) as it is not covered by my maintenance plan. Nowhere in the maintenance plan is this aspect addressed - this is pure daylight ******* by Audi. Beware of so called motor plans by Audi as it is not worth the paper it is written on
