Extremely unprofessional and late delivery

I contacted a company named The Gate Motor Guru (www.gatemotorguru.co.za) in order to put a gate motor on my newly erected front yard fence gate. They told me they could do the job, however, the actual work was outsourced to a company by the name of Amalgamated S****s and Technologies (ASAT), without my knowledge. I received a quote and paid 80% deposit and was told that the job will be done within the next week. This unfortunately did not happen as every week there was a new excuse, ranging from wrong motors, wrong timing, other emergencies etc. This continued for 7 weeks with now solution. I contacted the Gate Motor Guru and a mister Shawn told me that ASAT is not part of his company and that he can do nothing about it. Every time I contacted ASAT they said they will come tomorrow, but they never did. It is only after threatened both parties with a law suit that I got a reaction. ASAT finally did install the motor 2 weeks after that. I see The Gate Motor Guru has afterwards updated their website to state that they are only a referral agent and not liable for any damages. I would advise anyone to stay away from both these companies.
