Quick Payment, but now can't get hold of them on any of their 4 numbers!!!

Tried to make contact with Mohamed Bhayla but to no available. Asked for a quick payment of R 2500.00 for a customised cell number, but it's been almost 2 weeks and can't get hold of him. Watch out as soon as you pay he basically ditched me. I initially paid R 2000, but then soon thereafter asked for an additional R 500.00 as he said he is "in trouble".
