Never in my life again. Willingness to rectify their own problems are unsatisfactory, you enter in a 12 month agreement only to find out that you can only cancel the services on completion of the 12 months and provide a months notice - essentially meaning you have to use their services for at least 13 months (unless you want to be in breach of their terms and conditions - for which they charge penalties) The contract protects Rent a Gardener and not you as the consumer - be sure you understand what you are signing. I will personally not refer any business to them.
They do good work but may have gone out of business as calls and emails are not answered. Have prepaid for services not rendered.
