SUBSTANDARD SERVICE: Deep Clean

PAID FOR A DEEP CLEAN, but a received a substandard service and not at all what was promised on their Facebook page. The two cleaners were suppose to clean my house thoroughly by moving (movable) furniture, and clean underneath, take of knick knacks on tables wipe it, clean switches, window sills etc. They both worked extremely half. At a stage they were actively discussing something and when 15:00 came they got ready to leave without completing the service. Before that they were laughing and chatting, totally relaxed, not in the least worried they won't be finished and not discussing any concerns of an incomplete service with me. When they walked in I specifically mentioned they do not have to clean INSIDE the kitchen CUPBOARDS, I indicated it clearly when I took them through the house. I gave instructions about the stove and oven. In the end only the stove, microwave and oven was cleaned, and when I said, what about the rest, the answer was: you said we must not do the kitchen. What a lie! They left: the countertops, the window sills, the outside of the cupboards, the external shelves, the fridge - everything that was mentioned to be part of a deep clean on their FB. Did not clean under the microwave etc. They cleaned ONE window. Ironically they remembered well that I said not to clean THREE rooms. They had only two rooms and the living areas. They refrained to clean underneath my bedroom furniture, and just one small window sill in the whole house was wiped thoroughly. They cleaned the bathrooms and stoops well enough, therefore 2 stars. The one, Lainah, rushed through everything in the beginning and then both Patricia and Lainah started to work slower and slower from 12:00, because they were leaving promptly at 15:00. They left many dusty/dirty surfaces behind. I contacted their employer, Letta Mothoa and asked her why the windows were left dirty when she clearly promises on her FB page quote "we never leave work incomplete" unquote. What a lie. When I asked Lainah what about the windows, when they were leaving, she gave me a snotty answer :"you will have to book us again." With what money? I saved up to afford this service. At first Letta was understanding and accommodating, saying "it NEVER happened before". And she will send someone to complete the windows. But everything changed when I sent her about 12 pics of still dirty areas - all the switches, window sills, underneath furniture etc. She accused me of implying they have not cleaned at all, and I corrected her that I am complaining about substandard service. I clearly stated what was left incomplete. She was rude, saying they have fulfilled their service, apart from the windows, she will not give my money back (which I have not requested). No supervision. No integrity from the cleaners, an attitude from one cleaner and the owner and no respect. The cleaners **** to the owner, and she chose to believe and protect them and their shoddy work. I wanted her to do a spot check! Yes, she did want to send someone to clean the windows and Yes, I declined, after I heard it was Lainah, which I did not want on my premises again, hence my windows are still dirty out of own choice.
