Poor Service from MBD

Good day

I'm not happy with the service I have received from MBD (Munnit Basson Dagama) Inc Attorneys , On Monday I called them requesting my outstanding balance, and there were able to email me the balance and I made an arrangement that they can debit the outstanding balance on the 25/10/2022 which they did debit as I promised, then now I'm requesting the letter that proofs that I have paid and my account is now not in arears anymore, they kept on saying we have emailed you the letter but when I check my emails nothing came through, when I call them now they just hang up on me .

I have explained to them that the letter I'm requesting I need to submit it to the bank, the reason my medical aid has forfeited and my grandmother, she's in hospital to do an operation so I need to pay the hospital in order for them to continue with the operation , The bank doesn't want give me money because it shows that I'm still owing Vodacom , I have explain to the bank that I did pay MBD and I was told to request letter as a proof of payment from MBD , but they are failing me , so I'm so terrified and stressed because my grandmother she's dying there in the hospital.

Please anyone from MBD if you read this please come to my rescue, you consultants are now hanging up on me because I have been nagging them to assist me, I don't know what to do anymore!
