Mens clinic Randburg

I am so dissappointed in Mens clinic.I rented a wall out toMensclinic and its contractor to advertise on,and make a monthly payment.October and november i didnt receive the payment.I called the contractor and the gentleman that works(with company'adverts at Mens clinic informing them about my dissatisfaction.Everytime i call they give me lot of stories.I spoke to the gentleman who works at Mens clinic,he told me that i must not paint the wall white as the contract ends November month and he will make sure that i get payment if my contractor is unable to pay me.When i call to inform him that i didnt receive payment he give me the run around,so many stories.I really need my payment for this 2 months and they must come and paint the wall white so that other companies can see that my wall is open for them to paint.Mens clinic i need this resolved please.I am unemployed and depending on these wall payments.Will appreciate if you come back to me with solution to this problem.This is so unproffessional
