No one says the issue is with Piriform per se. However, if Piriform wants to retain paying customers in India. then they need to followup with their Payment Gateway Service Provider (Cleverbridge) who is apparently not bothered about retaining Piriform customers in india.
And while Piriform and Cleverbridge are least bothered, otner companies including IOBIT, spotity, Netflix, Google, etc. are already India compliant.
Infact, last week, I have taken a subscription with IOBIT for its entire suite of System care on Auto-Renew basis.
Good Luck to Piriform.
