Disappointed with customer service

Poor customer service at the Vodacom store in Lakeside Mall. I have booked my phone in for repairs on the 13th of October 2018. The lady who helped informed me that the phone needs to be replaced and that they would have to order a new one for me and I should be able to get it the following Tues. Fast forward to the 31st of October and I still have no phone. I have not received a single message or notification or any updates about my phone. I have called the store atleast 6 or 7 times and each time the response is the same that they are waiting for the supplier or that it would arrive in the week or the next day. The last call, I was told that the manager will email the supplier and get back to me and still nothing no phone call or no information. If anything, as a loyal customer I would expect them to uphold their 7-14 day policy or atleast keep the customer informed as to what is happening that would be considered good customer service. This kind of service is not on and makes me wonder if I should continue supporting Vodacom or cancel my contracts altogether. It is very disheartening to know that if your phone needs to be replaced you need to wait for weeks before you receive a new one and still continue to pay for a handset on your contract bill when you don't have the handset.
