Credit Card Cash Back review: Wrong statement and threat to the wrong person

Najm credit card department is sending me since 6 month by mistake the statement from another client and threat me to take legal action if i don't pay. They ask me to contact - SHAHID KHAN - on the [protected]. I send him several emails already and no reply. 3 month ago after calling over 100 time to finally reach him, he told me that he is sorry for inconvenient and will sort it out. But i keep on received statement and legal threat every 3-4 days from MAF Najm credit card. Today i called him and his reply was... i cannot do anything sorry and he simply hang up on me. What a non reliable employee you have there dear MAF group. His Misbehavior his affecting your company. You want to hear the best part... I DON'T EVEN HAVE A CREDIT CARD WITH THEM
