RCA Electronics complaint: Very unprofessional customer service

I contacted the customer service via email about my tablet battery going out upon receiving an email back to fill out repair form i enter all necessary information including purchasing date and issue. At that time i was not notified i would have to pay for the repair so i send tablet in for repair so after not hearing an update on repair status or delivery date i contact the repair customer service from the time of me being on the phone they were very rude and continously interrupted me. So as of today i am notified that i will have to pay for repair and so it has not even been repaired or started upon yet so i suggest i no longer want the repair cause its so many tricks to it suddenly and that my tablet be shipped back the person over whom ever i spoke with gets on the phone and tells me well now im telling you that you have to pay or my tablet will be kept and says i just sent the email about paument forst off this was done so rudely and very unprofessional and then to top it off he hangs up on me
