Just as an update; The representative was kinda helpful this morning (approx 830am) and eventually said she would change my plan to the one requested. I’m not entirely sure it’s been done properly as my app now says it will change to a plan (8gb for £7) which isn’t the same as the one advertised (32gb for £7) which I was requesting, once my current plans renews next month.
But the most annoying thing is that ever since I spoke to her I’ve had no service, text or calls, and I’m having to use WiFi. Good job I’m at home. A second agent got me to reset my network setting which made no difference and eventually told me that there was a lot of congestion in my area and a lot of customers are connected to the same mast ! This isn’t acceptable.
