Garden maintenance - GARDEN GURU

Dont use Garden Guru for your garden needs, spraying of insects, lawn dressing etc. They do not return calls, do not respond to telephone messages etc. Quick to issue invoice once work is done, we paid upon receiving invoice, as we normally do for any other service we make use of. They came to spray for ants, two days later the ants were back in full force, needless to say, phoned, sent whatsapp, emailed, left various messages, and they do not get back. I asked them via SMS to refund our money so that we can use someone else as clearly we paid for a service that does not work. To date no response. Very bad for business!!!
