Trackers customer service is bad!!!!

I am extremely disappointed service. I called on the 30th of January and was promised to receive an mail within 24 hours with my performer invoice by Phumuzo Masindi and still nothing and today is the 6th of February. I followed up again today and was kept on hold for 10 minutes without any resolution by Nkalipho who told me that Phumuzo received the invoice from finance but did not send it. The lack of communication and follow-through is unacceptable for a service of this importance. Customer support needs serious improvement. I am still waiting for the performer invoice!!!
