Supersonic: Worst experience with a service provider I have ever experienced !

I requested a quote for two things (1) an additional 3 Plume devices (2) fix a faulty Plume device, that I bought from them.

I used their Chat Bot and 1st of all I had to beg them to send me a quote for a few days, once I received it, the quote was in correct. I had to wait another few days as they stated a different department had to do the quote, to get the quote. Once again I did not receive the quote to fix/replace the existing faulty Plume device. I just gave up on asking them.

When I eventually received the quote for the 3 additional devices, I requested that it be delivered to me, they stated a technician needs to come out, I told them I already have existing Plume devices, which was installed by them and that I do not require a technician as it comes at an additional cost. Once we got past that I spoke to a representative requesting the technician to come out on Monday 22 August 2022 and that they will call me to arrange a time.

When I checked in this morning 22/08/2022, via e-mail when they will contact me, I've not any response. I once again went onto the Chat Bot and then they stated a technician will not come out, they tried to call me last week. I stated that I have not received any calls from any Supersonic related numbers, as I have Truecaller, nor do I have any voice mails stating that they want to arrange a time.

The customer service is terrible, the way I feel right now, I want to cancel the order, as well as my subscription to Supersonic and go to another service provider.

For the price I pay for their service, I would expect way better customer service than I have received !
