Since I have had no response since your last post we have had no choice but to seek an alternative mobile broadband supplier - therefore please note that we intend getting a 2 week trial from Vodafone on their mobile broadband and if this performs as supposed to we will have no option but to cancel our contract with Three.ie. I have raised this issue 12.09.17 and as of yet had no acceptable response from Three on this issue.
We have escalated this to our technical team. I'm sorry for any inconvenience caused. The investigation is ongoing and we are focused on finding a resolution and putting that in place. As soon as we have this, we will be in touch with you immediately.
