Bad Customer service from Cell C and Hollard Insurance

After Cell C and Hollard Insurance put me through Hell for 2 months,my insurance claim was finally approved with the help of Hellopeter ,I paid my excess fee 7 days ago. Proof of payment was emailed ,I haven't received any call or communication about when will my device be delivered.I have never dealt with such unprofessional and *********** brand like Cell C.I have tried calling them to follow up ,you hold on for a long time to speak to the call Center , when you get disconnected they dont even border to call you back, What more do i need to do to get a good customer after i have been with this brand for 8 years.
