Bank Bali Visa card

Bank Bali Visa card

I am a Bank Bali Visa Card holder and I have had an unpleasant
experience using it.

One day I had lunch at President Hotel's Kahyangan Restaurant.
I paid with my visa card and signed a safe slip for Rp 149,314.
But when I got my bill from Bank Bali it was for Rp 203,764. I
faxed a copy of my sale slip to Bank Bali and they agreed to
debit that amount until they cleared the problem.

Then I contacted the restaurant. The answer I got was
unethical. According to them, there was another bill for Rp
54,450 which the cashier forgot to charge me. The cashier had
contacted the bank, requested another authorization for the
lesser amount and crossed out the figure on the sale slip which I
had already signed, replacing it with a new figure without my
knowledge nor my approval. The restaurant never tried to contact
me to explain their negligence.

My questions are: Is it legal for a seller to cross out and
change the amount of a sale slip which has already been signed?
Is it acceptable for a bank to receive a sale slip with a
crossed-out figure?

Due to the negligence of the restaurant's cashier, Bank Bali
charged me interest, delayed payment and for a copy of the sale
slip. Even though Bank Bali sent me a letter explaining the
cashier's mistake, I think it was unfair. I have faxed twice my
letter of discontent to Bank Bali but up to now I have not
received a reply. I need an explanation from Visa Card
International.
