Refusal to cancel Debt Review

On 24 Apr 2025 I emailed Debtco to cancel my Debt Review since my financial situation has changed. I received a call that my last deduction will be in July but to-date the deductions haven't stopped. I tried several times to call on all the numbers they provided in their SMS communication ***, ***, ***, ***, and ***, but none of them are going through. All my emails are also not being responded to. I think this is a deliberate act to ensure that I remain their "client" and keep paying them money.
