*********** Service very disapointing

Their system is not good when it comes to serving customer it confirmed that the turnaround time would be completed by 31 August To date, I have not received any communication regarding the status. I have contacted your call centre on several occasions. I spoke with an agent, Linda yesterday who advised that the matter would be escalated and that I would receive an email update; however, I have not received any correspondence. I called again today and was provided with the same feedback, but no progress or update has been communicated.
