Disgusting customer service from King Price - I would give them negative stars if possible

I am deeply frustrated and furious with the terrible service received from King Price Insurance. I was in the process of purchasing a brand new vehicle and contacted them for a quote last Monday, which I was immediately provided with. After providing the only relevant remaining information (being my bank details) to the sales consultant last Wednesday morning, I was informed that my policy had now been concluded telephonically and that I was covered by King Price (despite not having collected the car from the dealership yet). I then requested a copy of my policy as well as confirmation of cover from King Price on an urgent basis to submit to my bank for vehicle finance purposes (without which documentation I could not yet collect my car and would essentially be insuring a car that I did not yet even have in my possession). I followed up regarding receipt of the policy multiple times last Wednesday, which I eventually only received late Wednesday afternoon. Upon receipt of the policy, it was apparent that many details were reflected incorrectly and the policy further stated that in the event that the incorrect details were contained thereon, there would be incorrect cover. In order to rectify the policy and collect my car I immediately contacted King Price and informed them of the errors contained on the policy, the correct details in respect of which had all been provided to the sales consultant last Monday. I was then informed that the policy would have to be referred to their ratings department due to the details having been captured incorrectly by their sales consultant and they would contact me as soon as possible to inform me of the outcome. I followed up later last Wednesday afternoon but they could not provide me with a timeline or assistance. I missed a call from King Price late last Thursday afternoon and when I attempted to return the call I was informed that the relevant person had left for the day. I was not able to collect the car but my premium and initiation fee were both deducted off my account last Thursday. Last Friday morning I contacted the relevant person and was told that King Price could actually not cover me at all bearing in mind the correct details which I had provided to the sales consultant on Monday. Thus I was left in the position to start from scratch in looking for an insurer 5 days later, having a premium deducted for a car I did not have and still not having a car a week later through the sole cause of King Price. Further to the terrible service experienced above, I sent an email complaint to their client care department regarding the above events last week which I have not yet received a response to. In ADDITION, I have tried to follow up this week regarding the refund of my premium and initiation fee and have not been assisted at all. I would never insure my car with King Price in future and would give them zero stars if I could. What a huge waste of time and effort in addition to all the stress and frustration experienced due to their useless staff and service.
