Poor service results in dirty washing

I logged a call via Samsung to obtain the services for repairs of my washing machine. They logged the call with MM All Electronics and provided me with a reference number. I received an automated sms message saying my appointment is booked for 28/11/2019. Followed by a message saying if you cannot make it please call and their number. I phoned and spoke to Petros who was very helpful, however, you have to pay the call out fee of R550 upfront or cash when the service man has completed his assessment. The next day when he reports to the office they will check if they have stock available. In my case they didn't. They will send me a quote via email and I should pay 50% before they will order the item/s. Once they have received the part/s will they again communicate with you for the repair to be done. There is NO urgency. In the meantime I am stuck without being able to do any washing. An issue such as this can take days or even weeks........I guess if there is a next time will not make use of their services. I am sure there are many more service providers who will jump at the opportunity to assist!
