Do you want to connect the gas or exchange the cylinder? Then gather your thoughts and be patient! Everything is not thought out from the word at all, you can get stuck in line for hours on a minor issue, exchange a balloon is still that epic in three acts (blissful sexual). The conclusion is to contact only for a serious reason, or if you are retired and like to chat in queues, then WELCOME!
Try calling, the battery will run out and every time something is changed, the big elephant slowly turns around and this one is still covered in papers.
