Cellc disappointing service

I paid my cell c contract on the 3rd, sent proof and everything to the collections department, i got numerous calls that my account is in arrears, they told they will help allocate it, more than 16 days later im still waiting, i keep sending them emails i just get a response from lerato, and nothing happens yet everyday they are able to call me and say i owe but can't take time to reslove my issue after i sent proof of paent so many times, obe asked them to givey query to someone else because mine is not of high importance to Lerato,this service provider is so disappointing they dont even care
