Using BLS Coveyance law firm.which is in Green acres Newton Park Port Elizabeth The house was sold successfully new owner moved in, however the BLS Coveyance law firm did not pay me my money from the sale of the house they have gone to the extent of blocking my calls . I called the firm asked to speak with the Director Mr D Langa my matter was transferred to Miss Elona she said it is the Principal of P.E properties who is at fault Mr Tandai that is why I have not received my money the BLS Coveyance law firm together with P.E Properties are a *****.
