********* behaviour from Virgin active

I received an email that my contract would be expiring at the end of May. I contacted Virgin active on the 24th of April to cancel it. I spoke to a lady called Namia and she confirmed that my contract was cancelled. My account was debited on the 28th of May. I spoke to a lady called Thembisa who assured me that it was the last instalment. I also spoke to Elf. I see now (28th June) that my bank account was debited again. This is ********* and unacceptable.
