THE WORSE SERVICE EVER

I am so angry with Discovery Life. Feb 2020 i asked if they could change my debit order to scheduled because i was struggling financially and i was ignored. Then Apr 2020 i asked again and was told my acc is behind and needs to be settled, which i did.May 2020 i asked again and was tld to write a letter to that extend which i did (i typed it), but was told that i had to write it out, take a pic with my phone.This i did on the 4th of May 2020. Ever since then i would receive sms's that my acc is not payed, and i'd respond that i payed it via scheduled payment. I got angry at the end of Aug when i received yet another one, went into my bank acc and found returned debit orders. Now they are playing cat and mouse with me. Imagine receiving an email that my policy is cancelled. Who im asking with tears in my eyes requested cancelation of my life cover, please tell me.....DISCOVERY LIFE I WANT YOU TO REIMBURSE/REFUND ME THOSE RETURNED DEBIT ORDERS.Hope this is clear enough.
