Radio not working and fitted properly

Disappointing service by SOUNDLOADER: - Good day all new customers or potential customers. Please be aware that the service you will receive from Sound Louder Tebogo is pathetic, as I have been waiting more than 9 weeks from the date of deposit payment that was done on 28/06/23, for my radio to be installed. Eventually, the radio was installed on 06/09/23 but to date, it is not working. I previously bought 3 Android aftermarket radios from them with no issues at all and therefore decided to get one for my BMW E63 as well but this time I was very disappointed in the service received. When I ordered the radio I mentioned to him that because my car doesn’t have an Aux output he needed to order a separate Aux modulator before it would work. He assured me that the radio will work and I don’t have to worry about this. This is now months later and a promise was made that this will be sorted on 16/09/23 in the morning. On arrival, he couldn’t get the radio to work as the local modulator didn’t want to pair with the aftermarket radio. At this stage I can't use the unit at all, no signal for the GPS as the antenna for that was placed in the dashboard and can't find satellites, no sound as the unit is not compatible with the original sound system. If needed please contact me privately if you need proof of WhatsApp conversation, pictures of the installation as is and time frames. Regards Fire Access Control Networks Pty Ltd
