Deposit to my money account but still no reflection after 14 days

There was a deposit done to my old mutual money account on the 7th may 2018 and 2 days later I called the call centre money account to ask when it will reflect in my account as the deposit was coming from absa and generally it takes 3 days to reflect well not in this case. When I called on the 3rd day which was the 10th may they told me that it should reflect the evening or early the following day, I complained that why it was so long and was told to send my proof of payment through which I did, but when I saw nothing was in my account again the following day I called again the 11th may and was told that my proof of deposit slip was not received so I sent it again then I did discover the person that sent me my deposit used the correct account number but used old mutual instead of bidvest bank and there is where is all began... I called the 14th may and was told it was escalated but they missing information of the other account holders account number to track the deposit from them to me so if I never called I would have still been waiting on something to happen which would have been nothing, I gave it two days since I thought bidvest and old mutual are in partnership with banking so it should get sorted out but to my surprise on the 17th may I called again and was given false hope that my money will be allocated to my account that day, which nothing happened I called again on the 18 th may and was told it would reflect that day or early Saturday morning, the 19 may called again as was told now it takes 48 hours to reflect and it should be abit later, I called again on the 19th may and was then told it will be close of business today or monday... Monday will be the 21st may from a deposit that was made on the 7th may, and everytime I am told the next day and the next day, this is so frustrating they cant be re**** on, how hard it to allocate money to a persons account, if they want to grant you a loan you get it within a day from different banks but if it is your own money they delay it why???? What type of company is this so big yet no customer service at all and as for the management of money account call centre hopeless and useless they dont even know them selfs what the **** is going now.. For anyone that reads this please dont ever open a money account you will be sorry if someone does a deposit and one thing is incorrect you will have total frustration and it will be with that dont give a damn.
