I have just received 2 unusual texts from Orange.es - both indicating that I have requested a premium service followed by 2 more texts giving PIN codes to activate said services. I have definitely not requested any premium services. I have contacted Orange and received a standard response saying they'll reply within 48 hours. Has anyone else had similar messages?

I've had the same Orange payg number for about 8 years without problems. I don't keep much credit on the phone anyway so there isn't much scope for anyone to rip me off but I'm curious to know what's going on.
