Welcome to the community!
I would love to help. I'd like to know what device is used on the speed test ?
Have you tried to run speed test using a desktop/laptop connected via Ethernet/LAN cable?
Kindly, PM me your account details (Username/Customer ID or Contact number associated with the account)
Thanks for sending me your details, @Jchng129.
I made a few test on your service and it is currently connected for 3d 12h 43m.
I would like to arrange a call from one of our Technicians for further test and investigation.
Please let me know your best contact number and preferred time today.
