@SM Hello there, hot-spotting isn't ideal for you. Has your plan updated on My3?
@SM I understand your frustration and I'm here to help you the best I can. Going by your post, your Billing Cycle date is the 15th, right? You placed the request in plenty of time for it to change. It is very curious that it didn't change over and went to 20GB plan that is no longer available on our systems to apply. This will absolutely need further investigation. I'll need access to your account, please send me a PM with your broadband number, full name, address, and date of birth. Thanks
