Insurance.. More like *****

I have an existing car insurance with psg insure. For the months of May, June, and July, I have manually made payments. And from August, I had sent through my account details, so the premium would be debited from my account. Fast forward to October, I receive an sms, saying my insurance has been cancelled. Have called in, but someone was meant to call me back, it's been over a week. Tried calling, none of their numbers work, even called road side assistance, who tried to put me through to head office, but the lady advised me head office was diverting the call back to them. Not sure, but this is ridiculous, not even receiving calls, to clarify their process.
