I have been a Zipcar customer for a few months and while I have no issue with the service itself, every time I need to contact customer service on the phone I have had a terrible experience. I’m not sure protocols but I feel extremely disrespected by the tone of discussion every time I ask for assistance. Today, I asked if I could apply a coupon code for driving credit for an upcoming reservation where I just forgot to input it at checkout. The representative said I have no code and they cannot help me. I asked if she should look up the code I have in my email and her tone got progressively ruder as she said there’s no code at all for me and she would not be able to look up anything. While I tried to tell her I have an exact code in my email she seemed to refuse to hear what I was asking and kept saying I had no credit. I understand if she is unable to apply the code after the reservation had been made, but the way she explained it to me was extremely condescending and when I mentioned her tone sounded a bit rude she doubled down and refused to help me even more. This is not unlike other interactions I’ve had with representatives. While I like Zipcar, there’s other car sharing services where I’m sure I would be treated with respect and am considering terminating membership. I would like this issue resolved by possibly training staff better at customer service or even basic interactions with customers.
