I just left an O2 shop, they insist I have to purchase a 3.5GB cross blister at €9.99 in order to purchase for O2 prepaid M plan. Instead of paying just €15, I ended up paying for €24.99.
Can someone clarify this because the online store doesn’t have this pre-requirement. What can I do to get an refund because I don’t need another 3.5GB.
Thank you!
