Impossible to trade on unaligned charts, lost all my trust.

On Friday morning their indices opened with massive gaps to the upside, whilst on other brokers the indices opened with small gaps to the downside. It is impossible to trade on their indices' charts, which are no longer aligned with the market. I have attempted to get clarification from their Customer Support, who only undertook to perform a thorough investigation into the chart discrepancies. I have also lodged a complaint to their Complaints Department, however I still have not even received an acknowledgement of receipt of the complaint. The Complaints Department has 10 business days to reply to complaints, which I feel is so unfair towards a costumer, who requires urgent clarification and resolution. Such a massive and unaligned opening gap further creates massive drawdowns on traders' accounts and has an adverse effect on available equity. I am reluctant to trade from these unaligned charts and especially when there is now suddenly such massive opening gaps in price. I am also entitled to cash back rebates on my account, however it was unilaterally stopped. I am currently awaiting also feedback in this regard. Fair treatment of customers is supposed to be a core value at CM Trading, however I feel that this is not the reality. I sincerely hope I can find resolution as my next port of call is to lodge a complaint with the regulatory body, The Financial Sector Conduct Authority. I have now been for almost 4 years with CM Trading and unfortunately our relationship is now nearing its end.
