Double Billing

Cartrack fitted a tracking in my car on 16 May 2022. I made pro-rata subscription payment of R123.88 on 17 May via Magtape Debit Cartrack and R219.00 for the month of June on 01 Jun Magtape Debit Cartrack. Last week I received an sms with prompts to pay the R219.00. I ignored that sms as I had already paid. Yesterday, I realized there was an email on mu Junk mail advising that my service has been suspended due to non-payment? I've sent 2 requests and an email for them to provide clarity and no response received until now.
