Bad customer service

For the past two years I had a contract with Telkom Mobile. The contract was ending end August. One of the salesperson phoned me to upgrade the contract and indicated that you would be receiving a Samsung with more memory as upgrade. On 1 September the parcel arrived but with a Huawei tablet. I have since then trying to resolve the issue with no joy. I went to the mall or return the tablet but they referred me to 10210 number. 10210 Said it's not their problem and they referred me to 10213. 10213 referred me to a Mobile company in Cape Town. The latter said they have no record of my transaction. I sent telkom a message over the internet and tried live chat. Nothing helped. I phoned the number on the slip they gave me. The woman on the line couldn't understand my situation and she cut my call. She refused to even take my ID number to see who the client was. I'm trying for a whole month resolving the issue with no joy. Please be aware of taking a contract with Telkom Mobile.
