Appalling service

I have had enough of this company on the 6th of March I sent my car to the assessment centre and was told that I will get a response within 57 working days. To my understanding companies are supposed to honour SLA's that they have set themselves. Within this period I requested a follow up and Craig up until now still hasn't responded to the email. SLA is over due and still the assessment centre is not responding.<br> I want the following to be done:<br> I gave you two quotes use one of them and pay my money in my bank account within the next 2 days.<br> I no longer want emails apologising I want someone to call me and request my banking details and payment to be made that day. You wasted my time by requesting quotes and now my quotes are not good enough you are using a useless assessment centre which can't honour their word.
