business mobile line activation problem and no assistance

New business customer here, got internet and then 3 mobile business lines.  I am having a problem with getting two of the business mobile lines activated.  One line was accidentally activated to the wrong phone.  I contacted Comcast Business immediately and was advised to activate the second line with the other available number onto the wrong phone so then once they are both active on wrong phones they could do a swap of the numbers to the correct phones.  Well after going through the activation of the second phone it never went through on comcast end, it is in limbo now!  I then had a ticket created for the comcast engineer/tech team to fix the problem and push the number through to full activation but that has not happened yet.  They told me today it could take 3-5 days to get resolved!  I have been on the phone with comcast for the past two days trying to get this resolved and push getting it fixed, I have been transferred everywhere multiple times on multiple occasions and constantly speak to multiple people in other countries that cannot assist me, don't know what they're doing and that I cannot understand at all!  This is unacceptable as I run a business and need these lines fixed.  We have one number that is in limbo on comcast side and it has not been fully activated from their end, why does this take forever and a day to get something pushed through!  Someone from the engineer department needs to get this fixed asap!
