Pathetic service for simple service request

On 10 April I called Telkom 10213 to request that my internet line speed be upgraded from 10mb to 20mb at my home. I checked my connection speed on 15 April, but it was unchanged. However, I noted the job was closed off as complete on 13 April. I queried this on 10213 on 17 April. I was told by the sales department that my order was complete. I said that nothing had changed with my service. Sales said I need to speak to the technical department about that. I was transferred to technical were they confirmed what I already knew, that I was still on the same 10mb connection. Technical said they had not received any instruction to change my line speed and I needed to speak to sales. I called back and spoke to someone else in Sales and they raised an incident report to query why sales had the order completed and technical had no knowledge of it. I followed up on 19 and 20 April with 10213 and on both occasions, the Telkom system is down and they cannot give me any information on my requested upgrade. How can it take 2 weeks to process a simple line speed upgrade?!?
