Poor service from Cartrack

Went online Saturday 07 July 2021 to request quote from Cartrack for tracking divices for two of our vehicles. Flood gates of sales people contacted me to offer the deals after I already made sale to one of their salespeople. To fit unit into my cars was a process on its own but I waited patiently till units were fitted today 09 July 2021. Technician was on time to fit units, appointment was 08h00 and he arrived at 07h45 having driven from far east of Gauteng to far west in Carletonville. Units are fitted in both vehicles & I downloaded the app as requested by technician but to my disappointment, till now at 18h45 haven't received login credentials to Cartrack App. When technician left he informed me I will receive sms email for login credentials. Earlier during day caller from Cartrack said he will send me an sms to login but what happened to emails if their sms service is poor. I am totally disappointed in Cartrack after sales service and hope it's not how my relationship with them will be like going forward. Or is this a warning not to continue with their service???
