Canal Walk Vodacom Useless Service

I handed my Nokia 7 plus in and after assessment the repair centre advised me it was an OBF yesterday and the funds have been paid to the store for me to pick up my phone today. To confirm I tried calling Canal Walk Lower level Vodacom Superstore on *** 15 times in the morning with no answer(anyone reading this try calling them to see if they pick up as even Canal walk info told me they have a problem with the store as they do not want to answer their phone). When I got to the store I was told after recieving the wrong ticket and having to wait even longer that they have recieved the funds but the manager does not know how much they have recieved so I need to come back tomorrow to see if they are ready to assist me. This service is pathetic and I am very disappointed being a customer for years. I had a Nokia 7 Plus and want a phone with equal or better specifications and dont want them to pull a fast one and try to give me an inferior phone which they have a reputation of doing. All I want is a clear line of communication as its very frustrating not being able to call for assistance as I cant keep taking time off work to come to the store cause no one will answer the phone, then when I get there even the manager doesnt know whats going on. My Repairs Job Number is ***0.
