Boring sales call even at 20h31

I am so angry about the exact sales call center they cannot stop phoning me for a mere mgagazine which I started that I am not interested, just no 20h31 a lady bt the name of Zizipo phone me and tells me about the magazine. Which I have to pay every month, they can call more than 20 times a day, even if I told them I am not interested, they keep on phoning, imagine phoning someone at 20h31 which I asked her what time it is, she told it is beyond her control she is just doing her job, I am tired of being harrased by them, I make show that my account is up to date to avoid their nagging calls, but still it doesn't makes any difference, IS IT A SIN TO HAVE AN EXACT ACCOUNT WITHOUT THE BENEFITS?, IS IT A SIN JUST TO BUY WHAT I WANT ON MY ACCOUNT AND PAY IT, WITHOUT PAYING MAGAZINE, WHAT I AM GONNA DO WITH THE SOCCER MAGAZINE, WHICH A DINT EVEN WATCH. I AM TIRED OF YOUR CALLS OR I MUST OAID UP THE 300 I OWE I CLOSED IT. PLEASE ADVICE EXACT
