Billing **** 😒

I am so tired of telkom I don't know which network I can change to. The billing department is a ****. I keep receiving a bill saying that I have sent sms that costs R5 to R10 each but I have 750 free sms I receive on my contract I am told that the sms are sent to different network providers which is why they cost so much. But I have never sent any sms I have been calling about this issue for the past 3 months now. I am not getting any assistance 😒. I have been with telkon since 2017 but I am tire of the bad service from them. And also I am charged R30 for something called WASP Service I was told it's an Amazon subscription. I went on my app I canceled it but still I am being debited for it yet again this month. And the customer service is very horrible yooh. I really am tired and frustrated by this🚮
