Now what KING PRICE?

I've recently bought myself a new vehicle and so had to change the vehicle information, which went well and a prorata amount was deducted from my account and the car was insured but then by the end of August when the full premium was supposed to go off only an amount of R100 was debited, Why?. My debit order date has always been on the 1st of every month but on the 16th of Sept. an amount of R360 was debited from my account, Why?, which meant it didn't go through and was returned because there was not enough funds in my account. I phoned King Price on the 17th of Sept. to make an arrangement and i was told to call back on Tuesday the 22nd of Sept. which i did. The guy i spoke to told me that a prorata debit will be done on midnight of the 23rd of Sept. I checked my acc this morning, no debit was deducted. Phoned again this morning and there is no one that can help me because of the public holiday. Is my car still insured? Now if something happens who's fault is it gonna be? Definitely not mine, i've been trying for a week now to get it sorted out. Where is your wonderful service now KING PRICE! I want this sorted out immediately. Now i can't enjoy my long weekend because of you.
