The worst experience ever!!!

Ordered the promotional MiFis for 10GB online around the 15th March, only got a call from the sales team after 10 days. Then followed up until I got my delivery on the 4th April. I have worked for a telecoms company before and I know that a sim activation takes 24hours max. I called in and waited 30 min before my call was answered and was advised of the 72 working hours turnaround upon delivery. I followed up again on Monday the 9th April and waited 23min for my call to be taken only to be told that it’s escalated to a team leader for activations and I should give them 24hours to sort it out. 24hours lapsed and I called in again waiting for more than 20min for my call to be taken, then the agent told me that the turnaround time is 72hours for my escalation to be attended to. That’s when I spoke to the manager who escalated the matter again. I really don’t know what to do anymore because I’ve tried and tried to get this issues fixed but there’s no luck. I’m starting to regret doing business with them, this is utter nonsense.
