Unexplained charges on my cheque account

I started using their gold cheque account from last year and I can say nothing much changed in the way I've been transacting with my account. I noticed at the end beginning of January my account was sitting on two hundred and something when I checked my balance. And to my shock I am now billed for Value Added services and service fees. The same this is happening this month and it is getting worse the minus balance is more than last month. I requested a call back (last week already) via their FB page and via their website all I get is this response below.
