Dear customer, We're sorry to hear about your experience. From what we can see, your refund has already been processed. Even when a strong signal or 5G indicator is displayed, performance can sometimes be affected by local network conditions, temporary congestion, or limitations with our local network partners, which may impact data connectivity. We apologize for the inconvenience and appreciate you taking the time to share your feedback.
