Cancelation of contract/line

Very disappointed in the service I have received from Vodacom. I have tried taking a contract since December for theSamsung A53 which suppose to be a Christmas present for my son, the agent that assisted me did not inform me that the they had no stock i had to keep calling in to find out when the phone will be delivered & then was told phone it's on back order no stock will be delivered 1st week Jan 2023 which still did not happen. I kept phoning too find out when delivery will be made & empty promises no one calls back even though I was promised call backs. I called about 15 times. I then suggested that I will go in store & get the Samsung A53 since they have it avail as I was tired of waiting & no one nor the manager could confirm when they would get stock. I spoke to a manager who confirmed that is fine to do. The manager however did not advise the risks of cancelling the online order and applying instore now I have cancelled my order online & cannot get the phone in store appliaction & told I need to wait 90 days before I can apply again as there was an activation done in 30 days which is the contract i tried doing online. If i knew about this risk i would have never cancelled the inline order initially but the manager informed me tonproxeed and go apply in store. The manager themselves are not skilled & need some training. The service of vodacom is pathetic I would not suggest anyone takes a contract with Vodacom use another service provider they do not keep to their word, they do not followup nor have the interest of the customer. Very bad customer experience. The Managers are unable to handle escalations maybe not senior enough or do not know what they doing 🤔 😳 🤷 😅 DO NOT USE VODACOM. Take my advice. I'm still awaiting assistance since December. They are pathetic.
