Customer Care line not going through

I have asked the consultant to check the invoice for me and give me feedback after the sale. Last week I received a call from Telkom sales team and I bought a Huawei wifi router and I politely asked the sales consultant to escalate the invoice query for me.

On Wednesday, I tried to call customer care line on 081 180 and I can't seem to get through, the machine directs me to Whastapp chat and I can't get help there.

I also called 10210 billing department and I also get the same thing.

I have asked the sales consultant agent to send s call me back request because I need assistance.

I also need to sort out my sim card and account as it is new and I do not want extra amounts going off, so I need to set my spent limit to R0.00

Your urgent assistance will be highly appreciated and I will like to be contacted kn ***
