Pathetic service received from CELLC and I will not recommend these people to anyone

I paid my account on the 23rd September up until to date CELLC had failed to allocate the payment instead they updated my profile at the credit bureau and that really messed up my credit scoring . I have made numerous calls to their contact centre and sent proof of payment to them. The last proof of payment was sent to Kamogelo Malaka who also confirmed the receipt of payment. I just received the following sms from CELLC “Dear Cell C customer, please receive feedback for case no. *** ....without any details of the feedback. I regret why I made a business with these people whose intentions is to list people at the credit bureau once they don’t want to upgrade their contacts with them. I am fed up
