No client service

Checked that my contract was international roaming registered on their app before leaving for Dubai, since I left the country I had no coms and if I mail them threw wifi connection, they just send stupid replies like contact us from your phone or that I had to register before leaving for roaming. The rest of the time they bombard me with service servays.no efford to get me connected. The previous time I had days of battling to cancel a contract and use the number as prepaid. No client service at all.
