Highly disappointed and irate customer with liquity capital

I took a contract with Liquid since 2015 when I bought my car at some point I had to renew my contract and which was done without any issues. This year in March I had financial problems and missed one debit order. Instead of liquid capital to contact me as a long standing client to make arrangement who has never had issue before instead they forced another debit order I then contacted the to ask why would they force a second debit order in 15 days before my payday (to me logically it doesn't make sense what they did) but instead I was told no it's on the contract that you signed and unfortunately your contract has been cancelled..I begged them to re instate and debit my account twice on my pay but the answer was sorry we cannot help you. The sad part is the fact that when they want business all these terms and conditions are not explained to us propaly.. I have lost out on all the debit orders that I have paid... I have emailed them a complain on the 28th March 2019 up until today no one has come back to me... What kind of relationship that they buid with their customer... There is no relationship because as customers we do not have a say... Sadly my car is due for a service @ 60 000 km and I might not have funds to do the service... I am highly disappointed with liquid capital... I hate the day I signed a contract with them I feel like I have been ****med no one had responded to the complaint I sent in March... I am highly disappointed and highly irate with this company... I need someone to respond to this complaint and the one I sent to them in march... Thank you
