Worst customer service

I took a contract with Telkom where i purchased 3 phones and somehow my account was changed to bussiness account without my knowledge and i do not own any business. Later i began to experience problems when i wanted to do a sim swap in the store. I would be taken from pillar to post and was also told to go where i open the account which is in Alberton City. I went there several times and would find that there are off line and then i was told that the system automatically changes the account to bussiness if you buy more than one phone and tjey cant change it. Years later i tried to cancelb one of my numbers online and i was told to provide a bussiness letter that has letter heads and could be help. I went back to the store to complain and was given the same excuse. This month i tried to renew my contract online and i experience the same problem about how the cant assist me since my account iis under bussiness and i should go to the store. This has been an exhausting exercise and a very bad service from telkom. I have waisted a lot of my time and petrol trying to resolve this without any results. I even feel like cancelling all my contracts with telkom a go to another service provider. This has been the worst service that i have endured for years.
