poor service from call center/poor product

I had purchased a item (mag up) from a local phamacy and it did not work the same as we imagined it did not disolve and remained complete. We have been using this product many times before and found this to be strange. We then took it back to the selling store and they informed us to call the number on the package. We then called and informed them of the issue we are having with this specific product they requested a batch number and told us they will follow up and call us back. Few days past and I call again to find out if the problem has been resolved however I had to explain to a further two people at this so called call center what the matter was and keep providing a batch number. We have now givien up and would certainly not be purchasing this product again. This is poor consumer service and aftersales. Dont bother calling the call center as they are not helpfull at all.
