Extremely Bad customer service

I made an appointment with the company For treatment of ****roaches, it was done for me on the 5th February 2018, which was suppose to be on the 31st January 2018, the appointment was not kept i had to reschedule for the 5th February 2018. I only received my invoice on the 15th February after several calls & messages. I was told that the treatment works wonders and i was given a guarantee of 7 months.

I am still experiencing ****roaches even more in the other rooms than before. I called the person who did the treatment on ********** to inform him about the situation, he kept on saying he will call me back till today. I send an e-mail To the company as well, no response till today. Both contacts details are not answered.

I would love to have the treatment re-done or money back as i am not satisfied with what was done. customer service is so poor.
