A couple of interesting posts have highlighted both the positive and negative of the increase in customer service by brands on Twitter.

Andrew Grill has written a detailed account of his dealings with British Telecom in a post titled ‘Why call centres need to embrace Twitter and IM for customer support’. In it, he details a familiar bad experience with an endless chain of Interactive Voice Response systems and staff.

In the midst of it he contacted @BTCare who directed him to the helpline, but the eventual solution came from the section of BT.com which offers an interactive chat service with an advisor.

Meanwhile Dave Winer writes ‘Sorry I still hate Comcast’ – critical of the company which has received plaudits for using Twitter effectively to reach out as a customer service tool – in Dave’s case they couldn’t stop him getting ‘fired as a Comcast customer’ and offended him even more by telling him that they liked him during the process. Which is why Dave now prefers to avoid being cut off or dealing with Twitter reps for his AT&T account.

I’m not sure it’s about the tools being used, or even the amount of resource directed to each one (Andrew suggests that the 7 people he spoke to via the phone would have been better served monitoring places like Twitter etc).

I’m fairly sure it’s about customer service people being helpful and having the authority to solve problems etc proactively, whether that’s via the phone or Twitter.

It’s important to be in the place customers want to reach you, and equally important in the modern internet age to be monitoring for those people who might have a problem that they announce to others without contacting you directly.

But being aware of a customer’s problem doesn’t solve it.

I’ve had good experiences with some companies via Twitter – for example the chap who was running www.twitter.com/godaddyguy was incredibly helpful when I had hosting problems. He chased for answers, emailed, and even offered to call to ensure the problem was resolved – and all this was in the same time as it took to get a cursory email response via their online help service.

Partly, Twitter is a great tool for customer service, because it’s easy for companies to monitor, and quick for customers to use to share information, praise and complaints.

But partly, I think, the most proactive customer service people are eager and excited by using new technologies like Twitter, so you’ll tend to find more helpful people on there than in the call centre hiring whoever they can at the most cost-efficient wage.

I think we’re a long way from Twitter, Get Satisfaction etc replacing call centres – but I can’t wait for the day they do because it will enable everyone to highlight the proactive, useful, customer service staff from the bad far more easily, and mean that everyone gets a better service no matter who they’re dealing with.
