RCS Call Center Staff are the rudest ever!!!!! calling from ***

For about 2 weeks I keep on getting up to 40 calls per day from this one number ***, and every time I pick up there is no one on the other side. So today I picked it up once again and this time a lady on the other side greets me. I said hi and asked who it was and she said RCS. I said sorry you could not get thru previously. So I told her that this is probably about my account which was unpaid the last month due to me not getting paid in lock down and I asked her if she can maybe help with some sort of 'payment holiday', then this arrogant woman say;"....if you can give me time to speak, I will." I was friendly from the start and she is such a b*tch. RCS, U SUC****! I never skipped a payment even once, now you are treating my like ****?!!!
