Poor service from Vodacom device insurance

I have been trying to get Vodacom insurance to deal with my claim for over SIX weeks and I keep getting the run around from the I have requested on more than one occasion for a manager or supervisor to contact me but to no avail.. On the 13 of January a call log was requested from the original sales call but to date nothing is forth coming. I always have to call them no body there bothers to contact their customer.
