Review they ruined my startup because of their negligence

Three years ago, I registered a domain from HosterPK Web Hosting, and we also purchased so many domains and their hosting plans but because of their negligence and their unprofessional attitude. We shifted our domains to other hosting providers. Unfortunately, only one domain was remain registered with them, and that domain expired on 31st January 2018. I paid the yearly subscription fee on 4th Feb 2018 and filled their form as well against my invoice, And also sent them an email reminder to update my domain status. After that, I got busy with my other routine tasks. 20 days later they deleted my domain from their server on 8 March 2018, and I received their last email on 9 march 2018 with the status that they have removed my 3-year-old domain from their server, now I cannot redeem or claim it.
When I called them on the same day, they refused to help me out and asked me to purchase a new domain from them instead of my three-year-old domain. And they told me they transferred my payment to add funds because we didn’t know the payment we have received is against which domain?
My point is only one domain was registered from that account. I also emailed them to change my domain status on which they didn’t bother to reply me properly. And after deleting my domain from their end. They send me an email that I cannot redeem it. Why didn’t they notify me before 8th March 2018?
Because of these culprits, I lost my domain which is now using by some other owner. My three year’s investment got wasted as well. I will recommend to not register or buy any plans from them.
