A Seattle based Smartphone Company called HDC asked a software company SDC to develop software for them. The software company gave a total estimate of 10,000 dollars for a total work of 20 days. It was agreed between the two companies that HDC would be paying SDC 30 percent before the beginning of the work, 60 percent after the initial version and 10 percent on competition. After 10 days, of work SDC wrote a letter that the work will take more time since their chief software developer has left the company. After 15 days SDC wrote back saying that they would be only able to deliver the source codes and would provide an assistant developer who will finish the rest of the work. After 20 days, when HDC asked for the final version, SDC told them that it can provide them with 80 percent of the work and would like the 60 percent as promised. However, fearing non-completion of the project, HDC cancelled the contract and asked for a full refund. SDC has threatened to take HDC to court for a breach of contract. Required:

In the context of the Law of Contract, advise HDC, whether they can take any action against SDC and what appropriate remedies are available for the aggrieved party?
