Disrepectful Call Centre Agent - Delayed Claim

I have submitted a claim, for accidental damage to my vehicles head unit, a week ago. I took the vehicle for assessment on Monday 7th September, at 13:05 as instructed. I also submitted the quotation for repairs, on Monday afternoon as requested. To date, my claim is still pending. I called the call centre ***) 3 times this morning and had to deal with a rude call centre agent, by the name of Silindile or Sindile. She cut my call the first time I tried to enquire on the status of my claim, and when I called back she answered the phone, and I asked for her supervisor, she cut the call again. When I called back the 3rd time, my call was cut before being answered. I will not tolerate this unprofessional and rude behaviour from a call centre agent. I want someone from senior management to contact me, to explain why my claim is taking so long, and to explain what action will be taken against the above mentioned employee. The damage is affecting the normal operation of my vehicle, and I need it to be repaired ASAP.
