I am so disappointed and shocked at Bing.
The support is appalling, try ringing it you will get (I) they pick up the phone and then cut it off before you get to speak and you have to ring and go on hold again (ii) it says an agent will be with you soon then it goes silent and after approx. 4 minutes they cut you off or I left it for 10 minutes and then they cut it off. They claim there is an English call number but it goes through to India and you get the same appling incidents.
We spend a considerable amount of money with Google and decided to try out Bing, from day one the experience with Bing was poor. The export from Google they tried did not work it did not bring every advert and adgroup across, which is very serious.
The Negative keyword function only allows you to import 500 at a time then it got stuck and would not let me change from phrase to exact, plus they do not warn you that when you import negatives from Google they do not support broad match so I changes them to phrase which is very dangerous I am now having to work through 1000 negatives.
When you try to complain they either hang up or no one want to take ownership of your account or issues. It has been over 10 years since I experienced customer service as poor as this and I cannot believe a companys big as Microsoft can treat customers so badly, it is clear they have so much money we do not matter. Google is so much more professional and seem to give a damn about their customers, don't forget we are trying to give them money and they treat us like this so how helpful would they be if we had an issue... this is just my opinion based on my real disappointing experience, what a waste of time. 4 days later still no progress, the fact they do not even respond to other poor reviews says a lot about how much they care about their customers... what a shame so disappointed
