Poor Service

Trying to get my Samsung 'FIit e' watch and power bank, which is supposed to be couriered to me from Samsung, as it is their promotion through MTN. Been on hold for over 28 minutes, trying to speak to a consultant. Was on hold yesterday for over 15 minutes, and they still couldn't resolve my issue with the new A70 phone I bought. They aren't even aware of promotions that they are offering through MTN, and MTN advised me that it is a Samsung promotion. Not sure which company is more useless? Samsung put me through to their courier service, who told me that that they are no longer dealing with Samsung, as they gave to many problems. Very poor customer service.
