No la, I wouldn't say zero effort.
They probably have to work on a tight budget.
The mall isn't pulling in many shoppers lately and quite a number of tenants have moved out.

Maybe refresh tenant list is just to make it sound better because the fact is once the tenant have moved out the space is left vacant for months.
Some new store that's now in renovation I see is Daiso which will greatly help this mall.
Another is a kid's gym taking over Toys'r us and previous Gymboree space. It's HUGE space!!
2 new foot outlets and one that sells mixed items at ground floor with minimal reno done.

Rest of the tenants who moved out are still empty.

I've never been inside Glo mall. I heard only some makan and minum place there.
At night I saw many cars parked along the road.
Probably they patron the drinking place.
