Pathetic Service from Vumatel

My fiber was installed on 19 Thursday May. The PON light stopped blinking the following Tuesday 25th May. What followed was a series of passwords and usernames sms. But there was no internet connection. To this date I (02 June 2021) I am stuck with an internet that is not working. A ticket was opened on Thursday and 7 days later is has not been resolved. Contacting both Vuma and Supersonic has not resolved anything. I was given a turnaround of 24 to 72 hours on Thursday and today I have been told it takes 7-14 for installation. Interestingly today they sent me login details again but failed to attend to the ticket (ISP-477320. BD). According to the ticket the issue is no IP Address not Connected. Does it take a week to assign an IP Address
