poor Service from Honda Dealership

Recently sold a vehicle to Honda Sandton (North Motor Group). We were due to get R16K after settlement with the bank, but the salesman incorrectly paid only R8000 (strike 1). After undertaking to pay the balance he failed to respond to an email from my wife when this didn't happen (strike 2 & 3). In a follow up telecon he was defensive but again undertook to expedite the payment. Payment was again not received in the promised timeframe with the excuse that he was in a meeting (strike 4). He then sent a blank - no apology, explanation, etc - email with a schedule attached as 'proof of payment' (strike 5). The money subsequently reflected in our bank account. When I called the Dealer Principal to express my dissatisfaction with the poor customer experience he was more irritated by my call than concerned about the issue (strike 6).
