Appalling telephone customer service. Sold an upgrade by phone. Mistakenly given a new contract due to admin error. Now irreversible they say despite being their fault. Repeated incorrect guidance through whole process. Meanwhile had opened the phone / disposed of box so unreturnable (though keep having to remind helpdesk of this as they continually reel out return as an option via their script). Am 68 minutes into call with helpline and ‘options’ appalling - from waiting 9 days for investigation (transcript of original call etc) to see if they were at fault, to severing old contract on 30 days notice before porting over to new phone. Totally ridiculous. Needed new phone in first because old one faulty. Now stuck in limbo as can’t activate the new phone until investigation complete. And 2 bills now running in parallel. Very frustrating and totally unnecessary. Not recommended
