24 Hour Plumbing and Electrical Services seven weeks to provide quote

In 2018, I contracted, contractors, 24 Hour Plumbing and Electrical Services to seal my house roof. They did a good job and provided me with a 10 year guarantee. One of the conditions of the guarantee is that the roof be maintained (annual maintenance). In 2019, 24 Hour Plumbing and Electrical Services carried out the annual maintenance. On 21 September 2020, I contacted 24 Hour Plumbing and Electrical Services via email to provide a quote for the annual maintenance. This was followed with telephone calls. A followup email was sent to 24 Hour Plumbing and Electrical Services on 11 October 2020 and again on 23 October 2020. No replys to the emails were received. I sent text messages on 21 September 2020. On 01 November 2020, I logged a call on the 24 Hour Plumbing and Electrical Services website and also sent a Whatsapp messeage to 24 Hour Plumbing and Electrical Services that my roof was leaking when it rained heavily and water was entering our lounge which is carpeted. I got a response to the Whatsapp message saying that I will get a call the next day. I got a call on 05 November 2020 advising that a technician would come on 06 November 2020. The technician did not come on 06 November 2020, instead, I got a missed call. On 09 November 2020, I phoned 24 Hour Plumbing and Electrical Services and was told that the Technician would come on 13 November 2020 to inspect so that a quote can be prepared. I think the delay (from 21 September 2020 to 09 November 2020) to get a quote from 24 Hour Plumbing and Electrical Services is too long. Will await the technician visit scheduled for 13 November 2020 to better understand the reasons for the delay. Hopefully it can be resolved soon as the roof leak does require prompt attention, especially now in the rainy season. As 24 Hour Plumbing and Electrical Services provided the 10 year guarantee in 2018, I still want to use their services for the maintenance. I am just not happy with the delay though to quote - hopefully the repair can be attended to promptly.
