Pathetic Service and slow response

I've had Fibre installed at my house over a few weeks ago through Vumatel. Since the installation my service was activated on the 1st of February and working fine at first. After 2 days the blue light on the router started flashing and I've not had any connection since then. It's now been more than a week that I've been without internet after signing up a contract with them in good faith. I've had multiple e-mails saying a technician will be dispatched but have not heard anything since.

Please can you contact me immediately to sort this out. I do not see why I should ask for service from you when I'm paying you. Your internal ticket for this job is #43753.
