Poor Customer Service

On 14/12/2017, I went to Edgars Connect Bloed Str Mall to insure my cellphone not older than 7 days. To my surprise I received a call around April 2018 from Edcon HQ to verify my banking details because they were not getting any payment for my insurance of which was supposed to be on debit order. When I asked them to read the banking details they had, they read the card number instead of the account nr. This means the consultant at the shop captured incorrect information. What if then my cellphone was ******/ lost. It took Edcon more than 90 days to advise me that my debit order is not going through. Is this the customer service I am supposed to experience?
