UPGRADE NIGHTMARE
I have been trying since 04 May 2022 to upgrade my LTE Contract
I'm getting no joy and just keep getting reference number after reference number, 
Phoning them - no result get disconnected when "transferred to correct department"
Mails - Just get notification that the sales department will get in contact within 24 to 48 hours - sure it must be a typo should rather be within 24 to 48 DAYS

Reference numbers received with no return call or assistance to get this long o/s query resolved
************************************************************

Should get another one today when I follow up YET AGAIN
