******** locking of cash device by foneyam-the attendants are ignoring me

I previously connected foneyam about my locked phone which I purchased cash in 2024 at pep cell.My phone has been locked since 28th of April.They seem to have no solution about this problem,what I get is only empty promises. I'm tired,frustrated and traumatized.They are just playing games with me and I'm tired.Their response would be we can't help because you're not under our rental agreement but yet they locked while they know I'm not under their agreement.I have to pay bills but my banking app is there.I have money from savings account which I want to transfer to the main account but I don't have access to it.I'll never buy a phone from pep cell or ackermans when they still have this *****ulent company by their side 

Dear Foneyam management 

I am writing to issue a final demand before instituting legal action against Foneyam in the small claims court.
Foneyam has remotely locked my phone using your device control security software. I did not purchase this phone via a Foneyam contract nor did I sign an agreement with your company.I purchased my phone cash in 2024 from Pep Cell. Your representatives have already investigated this matter and accepted/admitted that this lock was placed on my phone mistakenly.Despite acknowledging this error,Foneyam has failed completely to remedy the situation and my phone remains locked and unusable.
Your ongoing failure to remove this restriction constitutes ******** deprivation of my personal property.it has caused me severe financial inconvenience and data loss.I require Foneyam to completely remove your lock-control software from my device before the end of tomorrow the 28th of May because I gave you the whole month to solve this issue but you failed. Failure to do so you will have to pay for the damages (my phone,airtime used to contact you for the whole month,data bundles and loss of financial income this issue caused)
