Bad service

Yoh i am not a happy customerat all i paid my burial at zamokuhle on the beginning of may then month end when i pay they are saying i am paying for the month of may again. I went there today to ask why are they saying i did not pay for may and the lady said there is no receipt in our book but i fail to understand why is she not checking on their invoices because they do hv the data of who paid and what not now they telling me month end i have to pay double. Zamokuhle you are bunch of ****mers m not happy at all
