Unfair credits

Hi i would like to lodge a complaint against my service provider.i have been a loyal customer with telkom for more than 8 years. i have been having connectivity issues regarding internet in my area. (Very poor internet connectivity. internet speed below 1mbps, telkom advised that my area has LTE.) i logged a call with telkom around november 2019. telkom didnt attend to my call, when i called the call center in feb2020 , they advised that they tried to call me and i did not answer and they closed the ticket on their side cause they saw internet usage on thier side. i then logged a new call in February 2020, i kept on following up on the case. after investigation from telkom side. the technician from the technical department advised me that they have a problem with the network tower in my area and they can only fix that issue in the next financial year due to budget. he advised that i can cancel my contract and be reimbursed or use the services with the poor network connectivity. i then cancelled the contract. i pay R840pm for this data contract. telkom only reimbursed me R93.i claimed to be imbursed from november 2019 til the contract was ended in march 2020. i am only claiming to be credited for what i didnt use in the 5 months. i get 200gb data every month altogether and i used under 40gb each month. telkom told me that the usage is high and they will not credit me for those months. i feel that this is unfair to me . i paid for my service and telkom couldn't provide me with the services due to a problem with their faulty tower. if i had the LTE speed i would have been able to use my internet service to its full capacity but i couldn't due to telkoms tower.

the reference number with Telkom for the credits is ***7 .

please assist me in this long standing matter. i would like to be credited fairly for what i didn't use in the 5 months. Kind Regards
