Over promise under deliver

I am very disappointed with my recent experience with Discovery Insure, my car had to be booked in on the 30th of October for some repairs. I contacted Discovery to arrange the uber benefit on Friday the 27th for the brief time that my car is at the panel beaters, spoke to a lady by the name of Boitshepo who advised me she has arranged and uber funds will available in my account within 72 hours. I call to follow on Tuesday as the funds are still not reflecting , i am then told it was await manager authorization. I advise the lady that i do not have a car and need this resolved ASAP as the internal delays should not be my problem, she advises that I will be authorized and given a 72 hour SLA yet again to which i express my dissatisfaction as this delayed was caused by Discobery and not me, she promised to request that the manager Charidan Lukay call me later in the day to assist with trying to escalate . To date noone has called me nor are the funds in my account . I sit here greatly disadvantaged by this as i am struggling to get around , this has caused a huge inconvenience. Regards a very frustrated and unhappy customer.
