uuurrrrggghhhh...
GoMo has the same level of customer service as eircom.
Applied Oct 21st, check last week and no confirmation of shipping of sim card showing. Contacted support by email form, they replied 2 days later saying that they would put a "priority on it".
Still not shipped last Monday. Contacted again, they replied, can't see why it has not shipped - we'll check and get back to you.
Decided to contact Three on their webchat and see if they'd match the price - within a couple of minutes and by providing my gomo order number, they agreed €10/month for life.
Bye bye gomo.
memo to self - never ever ever look at anything to do with eir again.
