Dially calls which is now seen as stalking

I've got huge problems with the RCS, for some reason my debit order for the loan didn't go off I had an unpleasant argument with one of the agents telling me I don't have money in my account which is a lie because my account always have funds available and all my other debit orders are taken on time now the call Centre agents calling me everyday and with all honesty this happens everyday, my number is dialed and nobody speaks, i am frustrated to the core, I have an account with RCS and I do understand that they need to contact me but everyday this happens and it's so bad that they don't speak, I don't know if they do that to increase their dialls but can it please be stopped. This is seen as stalking.
