Pathetic online service

I purchased a Honor90, from the Vodacom online shop. The phone is not working properly and I am within my 7days return period, however I can not get a hold of anyone to log a return. I have tried calling multiple numbers, 10 different contact numbers to be exact still to be transferred multiple times. After hours of being transferred, being on hold and calling multiple numbers I still have not been able to log a return. The service is pathetic I paid R13599. 00 cash for this phone. And it is within my right to return it, however vodacom customer care is unable to assist because they themselves don't know who to call.
