Vadcom customer service is bad

In December 2018 ,I went to Vodacom 4 u at Westgate Mall shopping for a phone , Vodacom had a special running of two phones at a price of one which are X2 Huawei Y5's for a price of R179 ,I then took the deal and collected the phones I gave one to my wife,I made sure that I insured the phones ,the insurance is underwritten by Allisom repairs,and I paid my contract on time every month,I had a unfortunate incident where we experienced loadshedding in the midnight hours and my phone was on the charger ,when I woke up the next morning my phone was malfunctioning it had some Chinese words on the screen and then it just switched off ,I decided to take it to Vodacom 4u at Westgate Mall ,I spoke to a lady by the name of Mary Mthethwa whom I explained the whole incident to ,so she took me through the process of how I can get the phone repaired ,she gave me a form to fill in then after I did so she advised me of a 21working day process where they needed to take the phone to the warehouse for repairs and they will let me know of when I can collect the phone ,I received an SMS stating I should make a payment of R3459.00 with 2days in order of them to proceed with repairing the phone ,I called Allisom repairs and they took their own precious time to answer the phone ,when they eventually answered they told me that they dont find and claims regarding my phone they didn't receive my phone and afterwards they just shut the phone on my ear while trying to get a explaination for all they said ,I then got another SMS saying I can go collect my phone ,I went to Vodacom 4u Westgate Mall and Mary Mthethwa handed me my phone however guess what the phone was still in the same condition it was in when I brought to the store to be taken for repairs ,Mary then said to me that"oops sorry they did not fix your phone cause you did not provide them with the contact number of that phone "that's why they didn't fix the phone ,no one cared to contact me to say they need to have that phones contact number ,I am still without a phone cause even this very day ,now is it fair because they advised me to wait another 21working days , I had to provide them to my phones contact number as they had my other number remember there's two phones ,so furthermore they told me that I need to make payment to and amount of R60 cause my simcard is not working it has a scratch on it and I can't use it ,so the thing I want to know is they always debit my account and find the money available as per our contract agreement but now it's not a good thing to stay without a phone for about 3months I'd say ,this is very bad customer service the worst customer experience ever ,I mean the staff is just lazy to contact a person for a mere cellphone number like really now!! I would not recommend vodacom to anyone it would be a waste of time really and money.
