Terrible service by Telkom Mobile for wifi services

I've signed with Telkom mobile early last year for their wifi. It was 80gb, 40gb day and 40gb night. Since lockdown I've been working from home and connecting work systems using Telkom wifi. The data would last me for a month. Since this year, the data only last for 2 weeks and I have to top up. When I top up by 10gb, it will last me for a week, since last week 10gb last for 3 days and this week it last me for 2 days, today I top up again with 10gb, it only lasted 5 hours. I didn't stream just my normal working systems that doesn't use lot of wifi. I tried to call the customer care dpt and no one can help me. I've been getting calls everyday to sign up another wifi with them.

Strangely, very strange and ******* act by Telkom Mobile. Can someone investigate this matter asap and resolve it. I need my depleted wifi to be restated.
