Avoid this company at all costs. They are completely unprofessional and Omar the person who I spoke to was also extremely rude. He was happy to send someone when he thought a female would be paying but when I told him upfront that the landlord would be the one paying so an invoice needs to be provided he stated that he would only come if I made the payment even though the landlord lives next door...

Unfortunately, the customer service did not meet expectations. There was poor coordination regarding timing, and the overall experience could be improved
