nitially, the item was advertised at a certain price, and I paid for both the equipment and the associated shipping costs. However, after my initial inquiry, I was asked about the required voltage for the item, which was not clearly communicated upfront. Following this, I received another message stating that the delivery could not proceed unless I paid an additional amount, which would essentially double the cost of the equipment.After being informed that the delivery cost would increase unexpectedly, I requested a refund for the amount I had already paid. Since then, I have made multiple attempts to contact you through WhatsApp, but I have received no communication or resolution. This lack of response and avoidance is highly unprofessional and unacceptable.I expect an immediate resolution to this matter, including a full refund of the amount I have already paid. Failure to address this issue promptly will force me to escalate the matter through appropriate channels.
