The CGSO has done nothing to resolve my problem with Aramex

Having a problem with Aramex about a package from Germany that I was overcharged on due to an incorrect weight that was entered into their system. I had no luck in trying to resolve the issue with Aramex SA. I then contacted the Consumer Goods & Services Ombud. Nadima Hartley from the CGSO emailed me for the details. Ever since October 2019 the CGSO sending my e-mails to Aramex and forwarded their e-mails to me - an exercise I've been through already with Aramex. Nothing has happened or changed and we are at an impasse. I still have the package that can be weighed as proof but Aramex has not once ask for the package to be weighed as proof for a incorrect weight that led to the incorrect charge. I've basically have given up on the process and write the money off, The bad thing for Aramex is that I will not make use of them again and they will loose out on a lot of revenue from me, because they do not want to admit that they have made an error.
