Rain 5G

My Rain 5G sim was delivered on the 10/12/21, it only got activated on the 15/12/21, I was out of town at the time. When I got home on the 17/12/21, only to find out there's no coverage. I logged a network issue on the same date and I was contacted by Rain on the 18/12/21. I spoke to an agent and he advised me to cancel the plan as there site is not 100% accurate with coverage when checking if your area is covered for 5G. My cancellation ticket was logged on 18/12/21. I have not received any feedback. I logged another ticket of cancellation on 29/12/21 and asked if my plan was cancelled. I got a reply on 06/01/22 saying that they said they have a high number of queries and they request my address and contact details to fetch their device. I received an email on 11/01/22 at 13:22 saying collection for the device has been logged. At 14:32 a courier is calling me to say he's here to fetch their device. I was currently at work, however, I responded to their email with regards to my refund because I cancelled within 7 days of activation. So until they refund me, that's the only time I will be available for them to collect their device.
