Meerkat Debt Review - Unsolicited phone calls (Blocked)

Meerkat debt review has phoned me once saying that they are phoning me with regards to my query to reduce my monthly payments. I explained to the agent that I did not request a call-back from them, she then proceeded to name a person which is not me, I told her that she had the wrong number and the wrong person. Someone gave my number by mistake. She apologized and the call was concluded. I received a WhatsApp message from them a few minutes later, asking me to please provide me with a date and time that would be convenient for me to talk to them about reducing my monthly debt payments. I answered them, explaining to them yet again that they have the wrong number and that I didn't request that they contact me and that they should please remove my number from their database. They then asked me "So you don't need help with reducing your payments"... So I proceeded to tell them for a THIRD time that they have the wrong information and the wrong number. I have since blocked the number but I am still receiving notifications that they are trying to call my number. I need them to please permanently remove my telephone number from their database and stop calling me.
