Lancet may cause high blood pressure!!!!

Lancet is supposed to be a medical related service provider, but ironically it is, also out of past experience, causing to raise one's blood pressure! Here is my latest ordeal with them. We have received by e-mail, a Tax Invoice/Statement on Saturday, 19 June 2021 about services rendered to my 86-year old mother-in-law. We have had a difference with their billing details and e-mailed them a query last Monday 21 June 2021. Sadly, my mother-in-law has passed away the next day. Whilst still in shock and bereavement, Lancet, instead of reply to our query, started last week to send very upsetting SMS's about an unknown outstanding amount, i.e. R534.30 (Account No M***7) which is in any case irreconcilable with our query as well as the amount on their statement . It is therefore suggested that Lancet must jack up their billing and accounting systems so that they can in future score a higher average Hellopeter.com rating! (We have e-mailed them on 27 June 2021 to inform them about the passing on of my mother-in-law and requested them to forward a final invoice for settlement). Hopefully, they will stop sending us upsetting SMS anymore. (Suggestion: It is not a complicated issue to fix - just configure a system i.e. whilst a query is pending, automated SMS's should be blocked!)
