Rentokil does not value residential customers

I booked a residential fumigation service from Rentokil. I paid R1003.00 before service can be provided.I was given an appointment for 15:00 Monday the 15th June. I arranged well to make it to the appointment. On the day of the appointment i get a call @ 14:20 from the guard house that Rentokil is at the house. I tell the guards to let them in and wait for me, and that i was leaving the office immediately. I drove like a maniac to get to my house @ 14:40, only to find that they had left. In this whole scenario, no one from Rentokil called me. i decided to call Lloyd who told me to wait till 16:30. I waited, no one came, no one called. The next day I expect a call for an apology or rescheduling but i received no call, instead an invoice claiming that service was rendered. I then saw that my business was not valued. I called them to request a refund. Naydia responded to my e-mail without even greeting me informing tht i should supply my bank statement for a payment that would be made in up to 2 weeks. On Tuesday i finally sent them my bank statement. I did not get an acknowledgement of receipt from them until i had to send them another email today. Appalling service indeed.
