TERMINATION OF MERCHANT FACILITY

I was contacted in Aug last year after attempts were being made to use a ********** credit card at one of my stores. I was on holiday at the time. I requested this to be investigated and they said an investigator will be sent immediately, but this never happened. After numerous attempts to sort this out nothing happened. I had to cut my trip short. All my accounts were frozen, even ones not belonging to me but to that of family members. Funds were withdrawn with no explanation
