Incompetence and negligence - one booking - several ****-ups !

I don't even know where to begin. One **** up after the other. Seriously amazing that SS is still in business. A colleague a while back had an annoying no-show experience with SS and I have heard several stories about low pay rates to staff (essentially profiteering from desperate people). A different colleague convinced me to give them a whirl as I am moving and needed someone to assist with an outgoing clean. I booked SS online and app**** a discount coupon my colleague had given me. The system advised that I would need TWO people for a total of 10.5 hours (combined) I also requested cleaning materials. The night before the booking AFTER 10PM I received a WA from one of the scheduled cleaners asking for directions ! Agrieved and irritated I reported this to SS as not even my family would have the audacity to contact me at that late hour - not to mention a business associate and service I am paying for ! I received a profuse apology and was assured that SS would chaperone the woman the following day. About 10 minutes late my intercom buzzed and ONE woman PLUS her teen/tweenage child arrived. I told her that I had not been informed that her child would accompany her and told her to leave. NO SECOND PERSON EVER arrived. I had explained at the outset that the situation is time sensitive and here I was with deadlines and schedules to meet (carpet cleaners were coming following day) I received an SMS - the gaul ! FROM SS to say that their Cleaner had not checked in and I should call THEM. I did so and got VM. I called a second time - VM AGAIn and I left a rant of a message. In teh afternoon I received a pleading placating call from a staff member apologising profusely and assuring me she would follow up constantly and INSURE a smooth service the following day. I FOOLISHLY agreed and postponed the carpet cleaner. The next morning a smart and hard working cleaner arrived. her second day on the job. Just her. No second person. She worked well and hard and then advised that she would be working only 8 hours and would leave at 16H00 (Arrival at 09H00 ! so, essentially SEVEN hours. I asked her to work an extra hour and she agreed but advised it would cost extra - I had paid for 10.5 hours !) When she left at 17H00 the cleaning was not complete - she was exhausted and I could not request additional assistance nor make SS'd faux pah her problem. On contacting SS about this they brushed it off saying I now had 2.5 hours in credit and then received an email TODAY spelling my name incorrectly and referring to 2 hours credit ! BEYOND useless an d completely pointless. PLEASE do not err as I have done - go elsewhere if you need assistance. Sweet South 'service' is beyond PATHETIC !!!!!!!!!!!!!!!!!!!!!!!!!!!! They wated my time, exploited my agreement and I am pushed now to resolve THEIR issue sbut, her - I have 2 hours CREDIT !!! Hell will freeze over before I waste another second of my time on incompetence and negligence !
