I WANT TO CANCEL THE ORDER

I thought that Telkom was worse but I did not realise that Vodacom wa worser with their service especially because I am a new customer I was expecting the best service. I have since been waiting for a call back from Londeka who is supposedly "working from home" as she was helping me with a new contract and the worst part is that I am panicking because I have provided my banking details for a Sim card that I will not even receive because she did not take the delivery address.I cannot be able to cancel the order with anyone else because she has to do it. I WANT SOMEONE TO CALL ME BACK ASAP!!.I NO LONGER WANT YOUR CONTRACT. I have even called back 3 times with no help and even sent an email-no response. I'll tell my brother to not even bother renewing his Fibre contract with you.
