I was in Northern Ireland (Belfast) and I bought an unlimited volume for 1 month for phone and internet for £30 from a "Spar" store. The seller was so nice and helped me unlock the SIM card and the package. 20 minutes later we checked the balance and it was only 20p left. We called the hotline and they just said we should have called a specific number first and had the unlimited pack activated. All attempts to get my credit or my money back were unsuccessful. I would have expected such an experience in a third world country but not in an European Country. They have neither replied nor refund me. They advised me only to buy a new data package, unbelievable. Just keep your hands off! Huge rip off!!! Never again !!!
