Looks like the Cashwagon Sri Lanka is closed their physical office since CBSL and authorities started chasing them and now calling the exisiting customers from various sources and abssuing them to pay even more even if they already paid the loan. very detailed investigation report available here about how they ruined people life :

Vietnamese media reported in June, 2020 that Vietnam police launched an investigation into Cashwagon Co. Ltd and Lendtech Co. Ltd., based in Singapore, for lending money at unreasonably high interest rates. Cashwagon has a presence in Sri Lanka, Indonesia and the Philippines, according to its website.
However, Cashwagon Sri Lanka is no longer carrying out any promotions since last month (October, 2020). Its website no longer allows people to apply for loans. When contacted, Samila Fernando, the CEO of Cashwagon who wished to be identified as the ‘former CEO’, said the company is dormant at the time being. As the reason for the abrupt closure, Fernando said it was due to the pandemic.

If you look at their site, still they enabled Payment gateways and wallets to force the people to pay more even they down't owe them. I don't understand how the heck the goverment and authorities are still allowing such daylight robbery.
