No luck with roaming data in Medellin

In Medellin Colombia and I signed up for roaming addition on light speed network. Over 5 days now I've basically had no service at all. Every once in a while I'll get 3g for a minute or so but essentially I've had no data. It says I'm connected to Claro.

I have my VPN set up as instructed, phone set to roaming turned on, network mode on global. I don't think it's a configuration issue because I do get service occasionally but it's so bad it's useless. Any ideas if there's anything I can do? Different network maybe?
