I reserved a Mercedes Benz B-Class car five months in advance, prepaying most of the rental fee and insurance, leaving only a €48 balance. The booking page only displayed this model in the same category. However, when I went to pick up the car, I was told that they didn't have this model, and I could only take a Renault Scenic. I asked if there were any BMW, Audi, or similar models available, and was told that these brands are considered premium and would require an additional €20 per day. I pointed out that the Mercedes B-Class I'd booked was also a premium brand, but the staff insisted they could only offer a Renault. Because the full insurance I bought from the rental platform was past the refund period and switching to another rental company on the spot was uncertain and costly, I had no choice but to take the car. To make matters worse, the remaining balance increased to €70, even though the contract clearly stated €48. They claimed their system showed the tax-inclusive price as €70. After reluctantly picking up the car, I contacted the rental platform's customer service, who informed me that the extra charge was not tax, but a fee for picking up the car 30 minutes early. Charging €22 for 30 minutes early pickup? I'll never rent from this company again. They misled customers by advertising a premium brand price for a Mercedes B but provided a standard brand car and charged more.
