O2 customer advisor searched for the solution on Google. Totally untrained stuff. Very poor quality of network /signal/data and it is expansive. Worse customer support! I spent today 49min48sec on the phone with an O2 advisor to solve a small problem ( 0345 number goes straight to my voicemail stopping me from banking ). The O2 advisor went on Google to search for the solution !! And problem is not solved and i have to wait for 24 hours for the technical team to get back to me!!!Plus this Lady argued with me which is the worse for being in customer service !! Ridicules!!! I have been with o2 for 10 years and this is not the 1st time it happened in the last year. im very disappointed!
