Breach of Contract

I have a service agreement with Solartech that is paid monthly and requires them to service my solar geyser annually.<br> The service is due each year in April which suited me perfectly because I want it to work optimally during winter with less sun.<br> Last year after some complaining the service was only carried out in July and was not as thorough as previous years (Pipe insulation was not replaced).<br> I expected the service to be carried out in April of this year again but as the end of June approached and still no service I mailed them expressing my disappointment.<br> Naidene Knife responded and apologized and assured me that it will be done. By 7 October I mailed them again, demanding my long overdue service and a refund from May as well as the cancellation of the contract.<br> On 9 October the technician sent me a sms that they will come the same day for the service. I rep**** that it will have to be before 12:00 because there won't be anyone after 12:00. He rep**** that they will try otherwise they will arrange for the next week. I have not heard anything since.<br> This is unacceptable. They know how to deduct the money every month but do not keep to their side of the contract.<br> <br> Kind Regards
