Is VVM ******** me????

Good day<br> <br> VVM has been calling me trying to collect for a Hospital i was admitted in back in 2015. because of the ongoing calls and sms's i paid my first installment early last year for an amount of R150, i told the next agent that contacted me that i deposited a certain amount and he told me it doesnt reflect. i then stopped paying After i told vvm to find my invoice. they stopped calling for a while.<br> <br> sometime this year a guy called me and convinced me that after i pay the next R150 my previous transaction would reflect, i took his word and i made a payment AGAIN. only for me to be contacted by a lady named SESI a month after my second payment and she still told me that i must pay the full amount of R611.30 after i explained my horrific story she promised that she would get back to me and its been 2months nOW, suprisingly the sms's just never stop.<br> <br> Now can somebody tell me where has the money i payed gone to? whenever you see my deposits what steps do you take , why hasnt my account been updated and frankly HOW do you expect me to keep giving you my money if you just ******** me like this.
