I'm just going to give up on CellC.
My speeds average 3-4Mbps and when I'm lucky 5-6Mbps.
Just received another call from their customer service to say that the technician said he cannot find any problem on the towers and they are not congested. I don't know how the technician tested it.
The said consultant told me that the speeds that I'm getting are the average for the connection

If getting speeds of 3-4Mbps is acceptable for CellC then I'm flabbergasted.
She told me that no speeds can be guaranteed.
I have moved the routers all over my house in every room with NO noticeable difference. The roaming is activated on the cellphone and routers.
The one tower that I'm connecting to is about 700-800m from me.
So I presume my 2 routers and my new cellphone must must be faulty as well as those of the other people in my area (/sarcasm)
The consultant just had this attitude of there is nothing that can be done about the speeds because there is nothing wrong with the towers. (According to them)
I think when it comes to service and putting in effort to assist customers CellC must be close to the bottom of the list.
