OK, I very rarely get annoyed enough to write a review. However I'm absolutely fuming at the complete at utter incompetence of Tesco mobile. I had a bill query regarding my simm only tariff. Which was sorted immediately, the operator then after chatting convinced me to take out a new contract "don't worry I'll write off the remaining 20 months of simm only remaining" I received my new Flip 4, lovely looking phone, the change over from the old simm to the new will be trouble free. The the incompetence starts, 4 days I had to wait with the tesco mobile staff telling me this never happens! Well it's happening to me. I called every day as I need a mobile phone due to my job!! 4 days later it goes live, then they want a pat on the back! Now today, I received a bill telling me I'm being charged for ending my simm only contract early... You said I wouldn't have to pay that?? What's going on? Your elbow doesn't know what your backside is doing. Now there going to listen to the previous conversations to make sure I'm not a lying... Your the ones telling me lies" this never normally happens" I have my flip 4 for 2 weeks, 4 days of which I can't use as the simm isn't live. Then after 7 days the phone won't open, but tesco dont cover this in their warranty! Because I didn't take their insurance out!! Come tesco up your game or just sell groceries. Most likely go back to O2 if this is the level of service that "never happens" If you're thinking of changing to Tesco mobile.. Good luck. Not a happy Geoff
