Vodacom is *****ing from me.......

I have moved countries yet Vodacom is still billing me. I have patiently waited out my last contract with Vodacom which was due to cancel in May 19. I contacted the business recoveries team, as I was then again billed in June. I was told that Vodacom bill in arrears and that June would be my last bill of R 800. Can you believe it, I have now been billed in July around R 1800 and nobody know what it is for. I have now also randomly received 2 further bills for ongoing contracts for August which I have never had in the past ever...... I keep e mailing the business recovery team to have this stopped and to have them refund me my monies and they just do not bother to reply or fix this, they just continue to bill me. When you go into store, they cant help you, when you call they say you must e mail. Now I have e mailed - where to now Vodacom????? Where to now??? You are *****ing from me!!!!!!
