Unsatisfactory Wedding Planner

Hi all, I was hoping to get some advice on how to approach a wedding planner who has not proved himself to be particularly helpful or championing our wedding planning process. We engaged him based off a friend's recommendation about 5 months prior to our wedding, and we are now mid-way with 3 months to the big day. At present, only our venue for the ceremony and reception is confirmed (both venues sourced by myself), and we are speaking with 3 potential caterers (2 of which were found by myself). Our planner has offered one suggestion for the bar hire and DJ, and refuse to provide other options when requested citing that the one they put forward is the most economical and trusted vendor. Obviously I understand if they have already assessed a few options and landed on one recommendation, but as a bride-to-be I would really appreciate looking at the other options as well.

Additionally, most of the planning work does not get initiated until we ask the wedding planner to find suppliers/vendors for XXX. Having to constantly chase and follow up with our wedding planners feels like we are the ones driving the planning forward and gives me very little assurance that our needs are being well looked after. We communicated our desire for more oversight in the process and have even sent them a tracker that we would like to use for updates on each aspect of the planning, and are awaiting their response.

However, if they are not receptive to our feedback and requests, I am seriously considering cancelling their services and requesting a refund (partial, even). Unlucky for us, we paid the fee 100% upfront and there is a clause in the contract saying that if we cancel their services, we will not be entitled to any refund. I was hoping to get some advice from this group if anyone has had a similar less than satisfactory experience with their wedding planner, and how that got resolved. Thanks in advance!
