Faulty products, zero customer service.

Order #480595 On 29 June 2022 I purchased an online product delivered a week later that was faulty. I contacted Tevo and was asked to bring the product to their office. They were not prepared to collect it from me which was very inconvenient and the precise reason I purchased the product online. On 8 Aug 2022, I got in my car and drove to their offices to be told that I cannot return it in-store and that a separate process is to be followed for online returns. I then asked for a refund and was told this was not possible. I was told a replacement would be sourced and shipped to me. The last update communicated to me regarding this was on 11 Aug 2022. I have a faulty unit that I cannot return, replace or get a refund for. The aggravation of dealing with Tevo "Customer Service" is astronomical, personal time and cost I have had regarding this purchase will ensure that Tevo will never receive another purchase from me. "Dear Consumer Ombudsman, I have a story for you..." I wish to deal with a SENIOR member of this organisation.
