Unclear rules mentioned in grt golden eleven scheme

Sir/mam, this is kavipriya from Kumbakonam. I have registered a grt golden eleven scheme for 11 months. Due to some personal situations I have discontinued it by 5th month and was about to take gold jewellery now. The grt gold eleven has the scheme of either amount based or accumulated weight based option and the benefits are no wastage. Now they are telling me even you can't take accumulated weight option since it is before maturity period. But now my claim is it is nowhere mentioned in the brochure that accumulated weight is not allowed if you take it before the maturity period. When I am asking them for it , they are mentioning the phrase of no additional benefits before the maturity period. I am saying now , first of all accumulated weight is not a benefit, that is my right as I have every month due and registered some gold at that day and moreover if you really think it as a benefit why dint you mention it clearly that accumulated weight is also one among the benefits
