Waiting Period

So I had Service plan with Motor Happy. Was told I had to wait for 4 months for all the debit orders to go off, before I can claim and book a service. Sounded fair so waited. Eventually got my service in December last year, no mess, no fuss. So during the middle of this year I thought I should upgrade to a maintenance plan(Service plan included)rather. They told me I had to cancel my current plan and start a new plan with a new waiting period. Now the waiting period for the maintenance plan makes sense, but having to wait another 4 months for a service again doesnt. I already waited initially and wasn't given the option to waive the waiting period or join/upgrade the plan. I paid my debit orders on the initial plan and on my current plan. Now I can only have my service on the 25th of this month but the kms on my car are going to exceed their threshold. So I am now forced to either not drive my car, or find another mode of transport. We are talking 2.5 weeks here. I am asking they waive my waiting period, considering I previously had a plan and upgraded my old plan. This is ridiculous and I dont see a way out! The customer service did not help and could find a solution, expect to tell me to 'not drive my car till then'. ***! I expect someone from management to contact me immediately so we can come to a solution or I will have to go further with this.
