Octa Networks - Not providing promised training study material

Respect Sir,
Grievance regarding Octa Networks who promised to provide as per my expectation of CCNA+CCNP+CCIE Integrated course which includes Training + Workbook + Written Study Materials (as per quotation provided attached, will provide mail he sent if needed) by their sales executive Aquib Sayed (Contact No:***********) but later when I paid fees of *****/-
*. The receipt was different than what quotation was given (attached *****/- + *****/- I paid).
*. I accepted to go ahead because they refused to refund saying it is non-refundable. I had no choice but to proceed with whatever they offer.
*. Started attending the training (Free training provided by them for CCNA + CCNP), which included *** free participants over zoom.
*. Training was not satisfactory and trainer (Jagadish Rathod) was asking for good feedback to be submitted on LinkedIn, Facebook & Twitter page of him & Octa Networks.if one wants to attend free training.
*. As promised when asked for Study material for training (as promised in quotation), they said they don't have any material.
*. On giving feedback that training is not satisfactory management didn't take positively & instead said they don't need my feedback as they have many feedbacks.
*. When I didn't find any way out I approached on LinkedIn (February *, ****) Arshad Dhunna & Joaquim Fernandes (Directors of Octa Networks), they promised that they would check my case & revert but no actions been taken.
*. Their official site is www.octanetworks.com
