Contract Phone to be repaired

Good Morning <br> <br> I have been dealing with the above mentioned agents to arrange the collection , drop off of a loan phone , repairs and collection of my current cell phone. I have been with MTN for quite a while and have always arranged the above, due to the staff strike they were unable to assist me it has been 2 months and still nothing.<br> I am being passed from one department to the next and they are all telling me to deal with the repair call centre. The repair call centre is referring me to every other department. I really do not know what to do ?<br> Please can someone help my contract and insurance is with MTN
