Can you give worse service than Vodacom? You'd have to try very hard

I upgraded my cell phone contract and received the phone I requested. Well done. You guys achieved the very basics. I couldn't get the phone to work so I called the call center and explained the issue. They asked if I wanted them to collect the phone or would I take it into a store. I agreed to take it to a store. I went to the Vodacom shop in Bedford center where the staff told me I can't return the phone to them nor will they look at what is wrong with the phone. The lady went to the manager and came out to give me a phone number for their contact centre. Many calls to the customer care department later and a manager called me back. Great, only problem, because Vodacom has such poor data coverage the manager couldn't have a discussion with me because the internet line kept dropping. Vodacom seems to hold poor service challenges. Maybe they find the worst service details online and challenge staff to do worse. That's the only explanation I can think of that anyone would give such bad service.
